What expression represents the volume of the cone, in
cubic units?
xx 3
O 2013
O 47x3
Answer:
A.
Step-by-step explanation:
Volume of a cone = ⅓πr²h
Where,
r = x
h = 2x
Plug in the values into the formula for volume
Volume = ⅓*π*x²*2x
Volume = ⅓*π*2x³
Volume = (1*π*2x³)/3
Volume = [tex] \frac{2\pi x^3}{3} [/tex]
[tex] \frac{2}{3}\pi x^3 [/tex]

True or False? A circle could be circumscribed about the quadrilateral below. c 80° A. True 95° B. False 85°
Answer:
False
Step-by-step explanation:
The circle could be circumscribed about the quadrilateral is false because the sum of the opposite angles is not 180 degrees.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners. Two pairs of congruent sides, and it has one pair of opposite congruent angles.
As we know, the circle can be circumscribed around a quadrilateral if and only if the quadrilateral's opposite angles add up to 180 degrees.
But,
80 + 85 < 180
100 + 95 > 180
Thus, the circle could be circumscribed about the quadrilateral is false because the sum of the opposite angles is not 180 degrees.

Find the probability that a randomly chosen point is located within the shaded region. Write your answer as a decimal, and
round to the nearest thousandth, if necessary.

Probability
Answer:
[tex]Probability = 0.25[/tex]
Step-by-step explanation:
Given
The attached shape
Required
Probability of locating within the shaded region
First, calculated the area of the shaded region
[tex]A_1 = 0.5 * base * height[/tex]
Where
[tex]base = 8cm\\ height = 6cm[/tex] --- given
So:
[tex]A_1 = 0.5 * 8cm* 6cm[/tex]
[tex]A_1 = 24cm^2[/tex]
Next, calculated the area of the complete rectangle
[tex]A_2 = Length* Width[/tex]
Where
[tex]Width = 12cm\\ Length = 8cm[/tex] --- given
So:
[tex]A_2 = 12cm * 8cm[/tex]
[tex]A_2 = 96cm^2[/tex]
The required probability is:
[tex]Probability = \frac{A_1}{A_2}[/tex]
[tex]Probability = \frac{24cm^2}{96cm^2}[/tex]
[tex]Probability = 0.25[/tex]

base = 40
height = 16
Area of parallelogram = b×h = 40× 16= 640
Answer:
the area of the shaded area is 160 cm ²
Step-by-step explanation:
Hey There!
so the first step in solving this problem is to find the area of the whole shape
This is a trapezoid and the formula for area of a trapezoid is
[tex]A=\frac{a=b}{2} h[/tex]
a = base 1 (20)
b = base 2 (40)
h = height (16)
now we plug in the values
[tex]A=\frac{40+20}{2} 16\\40+20=60\\\frac{60}{2} =30\\30*16=480[/tex]
so the area of the trapezoid is 480
The next step is to find the area of the triangle
To do so we use this formula
[tex]A=\frac{hb}{2}[/tex]
h = height (16)
b = base (20)
now we just plug in the values
[tex]A=\frac{16*20}{2} \\16*20=320\\\frac{320}{2}=160\\[/tex]
The area of the triangle is 160

A rectangular resort pool has a length of 45 feet and a width of 30 feet. A sitting area is attached to the pool and is in the shape of a semicircle with a diameter of 20 feet, as shown below. If the pool is filled to a depth of 5 feet and the sitting area is filled to a depth of 2.5 feet, approximately how much water is contained in both the sitting area and the pool?
Athletic Outfitters packs tennis balls into a cylinder with a diameter of 9.6 centimeters and a height of 39.5 centimeters. Each tennis ball has a diameter of 9.5 centimeters and there are 4tennis balls in each container. Approximately how much extra space is in the container?
Answer:
1 7142.699082ft³ (C)
2 1063.420642cm³ (A)
Step-by-step explanation:
Hey There!
1. So for the first one we want to find the volume of the rectangular pool and the volume of the semi cylinder
The dimension given are
length - 45
width - 30
height - 5
to find the volume we use
[tex]V=lwh[/tex]
[tex]45*30=1350\\1350x5=6750[/tex]
so the volume of the rectangular pool is 6750ft³
now we need to find the volume of the semi cylinder
the dimensions given are
diameter - 20
height - 2.5
so we find the volume by using the volume for a cylinder then dividing by 2
the volume for a cylinder formula is
[tex]V=\pi r^2h[/tex]
r = radius
h = height
to find the radius given the diameter we just divide by 2
20/2=10 so the radius is 10
now we just plug in the values and get
[tex]V=\frac{1}{2} \pi 10^22.5[/tex]
Note: the 1/2 is added because were finding the volume of a semi cylinder
[tex]10^2=100\\100(2.5)=250\\250\pi =785.3981634\\\frac{785.3981634}{2} =392.6990817[/tex]
So the volume of the sitting area is 392.6990817
Now that we have found the volume of each part we add them together to get the answer
[tex]392.6990817+6750=7142.699082[/tex]
2. For the second one we need to find the volume of the cylinder and subtract it by the volume of the tennis ball..s times 4 ( because there are 4 of them)
For the cylinder we are given the dimensions
height - 39.5
diameter - 9.5
Remember this is the formula of the volume of a cylinder
[tex]V=\pi r^2h[/tex]
r =radius
h = height
to convert diameter to radius we divide by 2
9.5/2=4.75
now we plug in the values
[tex]V=\pi 4.75^239.5\\4.75^2=22.5625\\22.565(39.5)=891.21875\\891.21875\pi =2859.100642[/tex]
so the volume of the container is 2859.100642cm³
now we need to find the volume of the tennis ball
to do this we use the formula
[tex]V=\frac{4}{3} \pi r^3[/tex]
we are given the dimensions of
diameter - 9.5
once again to convert to radius we divide by 2
9.5/2=4.75
now we plug in the values
[tex]V=\frac{4}{3} \pi 4.75^3\\4.75^3=107.171875\\107.171875\frac{4}{3} =142.8958333\\142.8958333\pi =448.9205002\\448.9205002(4)=1795.682001[/tex]
So the volume of the tennis bal...ls is 1795.682001
note: i multiplied by 4 because there are 4 tennis bal...ls
our final step is to subtract the volume of the bal...ls from the container
2859.100642-1795.682001=1063.420642
hope this helps :)

What did I forget to do in this question? What should the answer be?
Use only Quadratic Formula
[tex] {7x}^{2} + 9x + 2 = 0[/tex]
[tex] {x}^{2} + 9x + 14 = 0[/tex]
[tex](x + 7)(x + 2) = 0[/tex]
x= -7,x=-2
The mistake is in the first step. You seem to want to divide through by 7, but you only did it correctly with the x ² term. What you should have after doing this is
7x ² + 9x + 2 = 0
→ x ² + 9/7 x + 2/7 = 0
This step isn't actually necessary to begin with since the starting quadratic is easily factorized:
7x ² + 9x + 2 = (7x + 2) (x + 1) = 0
Then
7x + 2 = 0 or x + 1 = 0
7x = -2 or x = -1
x = -2/7 or x = -1
