Given:
The radius of the sphere is 6 in.
To find:
The volume of the sphere.
Solution:
We know that, the volume of a sphere is
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
Where, r is the radius of the sphere.
Putting r=6, we get
[tex]V=\dfrac{4}{3}\pi (6)^3[/tex]
[tex]V=\dfrac{4}{3}\pi (216)[/tex]
[tex]V=288\pi[/tex]
[tex]V\approx 904.78[/tex]
The volume of the sphere is 904.78 inches cubed.
Therefore, the correct option is C.

A right rectangular prism has a square base and a volume of 225 cubic centimeters. The height, h, of the prism is 9 centimeters. Find the area of the base, B. A. B. C. D.
Answer:
Area of base = 25cm
Step-by-step explanation:
The formula for the volume of a rectangular prism is:
Volume = length × width × height = lwh
for a square base, length = width
∴ volume = l × l × h = l²h
where:
l = length
h = height = 9cm
volume = 225 cm³
∴ 225 = l² × 9
l² = 225 ÷ 9
l² = 25
∴ length = √ 25 = 5cm
Area of base = Length × Length = 5 × 5 = 25cm

find the area of the semicircle (1/2 circle with a diameter of 10)
Answer:
39.25 unit²
Step-by-step explanation:
Radius of circle = diameter/2 = 10/2 = 5
Area of a circle = πr²
Area of ½ circle = ½ πr² = ½ x (22/7) x 5²
Area = 39.25 unit^2
Area!

Answer:
118.73
Step-by-step explanation:
Answer:
118.74 ft²
Step-by-step explanation:
First, you're going to get the are of the following shapes, one by one.
Area of A Circle = πr²
Area of a Rectangle = bh
Area of a Square = s²
Step 1: Let's find the area for the Circle.
Diameter = 6
Radius = Diameter ÷ 2
6 ÷ 2 = 3
The Radius is 3.
A = (3.14)(3)²
Simplify:
(3.14)(9) = 28.26 ft²
Step 2: Find the Area of the Rectangle.
A = bh
11 × 2 = 22
Area of Rectangle = 22 ft²
Step 3: Find the Area of the Square
A = s²
13² = 13 × 13 = 169 ft²
Step 4: Subtract the Aea of the Circle and Rectangle form the Are of the Square.
169 - 28.26 - 22 = 118.74 ft²

A quartic polynomial P(x) has rational coefficients. If 2 − i and-√5 are roots of P(x) = 0, what are the other 2 roots?
Answer:
2 + i and + √5
Step-by-step explanation:
Since P(x) is a quartic equation, it has 4 roots.
Since 2 - i and -√5 are two of its roots, then its conjugate pairs of 2 + i and + √5 are its other two roots.
So, its other two roots are 2 + i and + √5
For what value of x is the rational expression below equal to zero?

Answer:
I can only guess that by x^2-2x-24 you mean the entire denominator. In cases like this is is important to use parentheses to remove any doubts. For example:
(x+8) / (x^2-2x-24).
This rational expression is undefined at any x for which the denominator, x^2-2x-24, is zero.
x^2-2x-24 factors into (x+4)(x-6). The roots are -4 and +6.
Thus, the given expression is undefined at {-4,6} (set notation).

Find the volume of the cone-
Answer:
12.6ft³
Step-by-step explanation:
Hey There!
So the first thing we need to do is find the formula for volume of a cone
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
r = radius
h = hypotenuse
Now all we have to do is plug in the hypotenuse and the radius
[tex]V=\pi 2^{2} \frac{3}{3}[/tex]
2²=4
[tex]\frac{3}{3} =1[/tex]
4xπ=12.5663706144
And now we just round to the nearest tenth
so we can conclude that the volume of the cone is 12.6ft³
What is meant by the order of operations?
Answer:
Step-by-step explanation: The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Andrew has 212 coins, all of
which are either quarters or
dimes. The total value of the
coins is $44.90. What is the
value of all of the dimes?
Answer:
158 quarters
54 dimes
Step-by-step explanation:
Let d = no. of dimes
q = no. of quarters
10d = value of all the dimes since each dime is worth 10 cents
and 25q = value of all the quarters since each quarter is worth 25 cents
$44.90 = 4490 cents
10d + 25q = 4490 d + q = 212
- 10d - 10q = -2120
15q = 2370
q = 158 quarters d + 158 = 212
d = 54 dimes

i f N(-7,-1) is a point on the terminal side of ∅ in standard form, find the exact values of the trigonometric functions of ∅.
Answer:
[tex]sin\ \varnothing = \frac{-1}{10}\sqrt 2[/tex]
[tex]cos\ \varnothing = \frac{-7}{10}\sqrt 2[/tex]
[tex]tan\ \varnothing = \frac{1}{7}[/tex]
[tex]cot\ \varnothing = 7[/tex]
[tex]sec\ \varnothing = \frac{-5}{7}\sqrt 2[/tex]
[tex]csc\ \varnothing = -5\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]N = (-7,-1)[/tex] --- terminal side of [tex]\varnothing[/tex]
Required
Determine the values of trigonometric functions of [tex]\varnothing[/tex].
For [tex]\varnothing[/tex], the trigonometry ratios are:
[tex]sin\ \varnothing = \frac{y}{r}[/tex] [tex]cos\ \varnothing = \frac{x}{r}[/tex] [tex]tan\ \varnothing = \frac{y}{x}[/tex]
[tex]cot\ \varnothing = \frac{x}{y}[/tex] [tex]sec\ \varnothing = \frac{r}{x}[/tex] [tex]csc\ \varnothing = \frac{r}{y}[/tex]
Where:
[tex]r^2 = x^2 + y^2[/tex]
[tex]r = \sqrt{x^2 + y^2[/tex]
In [tex]N = (-7,-1)[/tex]
[tex]x = -7[/tex] and [tex]y = -1[/tex]
So:
[tex]r = \sqrt{(-7)^2 + (-1)^2[/tex]
[tex]r = \sqrt{50[/tex]
[tex]r = \sqrt{25 * 2[/tex]
[tex]r = \sqrt{25} * \sqrt 2[/tex]
[tex]r = 5 * \sqrt 2[/tex]
[tex]r = 5 \sqrt 2[/tex]
Solving the trigonometry functions
[tex]sin\ \varnothing = \frac{y}{r}[/tex]
[tex]sin\ \varnothing = \frac{-1}{5\sqrt 2}[/tex]
Rationalize:
[tex]sin\ \varnothing = \frac{-1}{5\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]
[tex]sin\ \varnothing = \frac{-\sqrt 2}{5*2}[/tex]
[tex]sin\ \varnothing = \frac{-\sqrt 2}{10}[/tex]
[tex]sin\ \varnothing = \frac{-1}{10}\sqrt 2[/tex]
[tex]cos\ \varnothing = \frac{x}{r}[/tex]
[tex]cos\ \varnothing = \frac{-7}{5\sqrt 2}[/tex]
Rationalize
[tex]cos\ \varnothing = \frac{-7}{5\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]
[tex]cos\ \varnothing = \frac{-7*\sqrt 2}{5*2}[/tex]
[tex]cos\ \varnothing = \frac{-7\sqrt 2}{10}[/tex]
[tex]cos\ \varnothing = \frac{-7}{10}\sqrt 2[/tex]
[tex]tan\ \varnothing = \frac{y}{x}[/tex]
[tex]tan\ \varnothing = \frac{-1}{-7}[/tex]
[tex]tan\ \varnothing = \frac{1}{7}[/tex]
[tex]cot\ \varnothing = \frac{x}{y}[/tex]
[tex]cot\ \varnothing = \frac{-7}{-1}[/tex]
[tex]cot\ \varnothing = 7[/tex]
[tex]sec\ \varnothing = \frac{r}{x}[/tex]
[tex]sec\ \varnothing = \frac{5\sqrt 2}{-7}[/tex]
[tex]sec\ \varnothing = \frac{-5}{7}\sqrt 2[/tex]
[tex]csc\ \varnothing = \frac{r}{y}[/tex]
[tex]csc\ \varnothing = \frac{5\sqrt 2}{-1}[/tex]
[tex]csc\ \varnothing = -5\sqrt 2[/tex]
The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet. What is the area of the backyard?
Answer:
150 square feet
Step-by-step explanation:
Step 1
Find the Length and Width of the backyard
The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet.
Perimeter = 2L + 2W
L = Length, W = Width
L = 5 + W
Hence:
50 = 2(5 + W) + 2W
50 = 10 + 2W + 2W
Collect like terms
50 - 10 = 4W
40 = 4W
W = 40/4
W = 10 feet
We find L
L = 5 + W
L = 5 + 10 feet
L = 15 feet
Step 2
What is the area of the backyard?
Area of a rectangle = Length × Width
Area of the rectangular backyard = 15 feet × 10 feet
= 150 square feet

The circumference of a circle is 147 feet.
Find the area of the circle, in terms of pi.
Answer:
Step-by-step explanation:
C = 147 ft. The relevant formula is C = 2(pi)r, and here C = 147 ft = 2(pi)r.
The relevant area formula is A = (pi)r^2. If we solve the above formula for r we get
147 ft
r = ------------ and so r^2 (needed to calculate the area) is
2pi
147^2 ft^2
r^2 = ------------------
4(pi)
147^2 ft^2
and so the area is A = ---------------- = 7203/pi
3 pi
C C^2
Alternative method: C = 2pi*r so r = -------------- and r^2 = -------------
2 pi 4pi^2
C^2 C^2
then the area of the circle is A = pi(r^2) or pi*-------------- = ---------------
4pi^2 4pi
(147 ft)^2
and in this case the area of the circle is A = --------------
4 pi
or A = 1720 ft^2

. Solve for x
10 = 5(x + 8)
Answer:
x = -6
Step-by-step explanation:
10 = 5(x+8)
=> 5(x+8) = 10
=> 5x + 40 = 10
=> 5x = 10 - 40
=> 5x = -30
=> x = -30/5
=> x = -6
