Find the volume and surface area of the composite figure. Give your answer in terms of pi
PLS HELP
Given:
A diagram of a composite figure.
Radius of cone and hemisphere is 8 cm.
Height of the cone is 15 cm.
To find:
The volume and the surface area of the composite figure.
Solution:
Volume of a cone is:
[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]
Where, r is the radius and h is the height of the cone.
Putting [tex]r=8,h=15[/tex] in the above formula, we get
[tex]V_1=\dfrac{1}{3}\pi (8)^2(15)[/tex]
[tex]V_1=\pi (64)(5)[/tex]
[tex]V_1=320\pi[/tex]
Volume of the hemisphere is:
[tex]V_2=\dfrac{2}{3}\pi r^3[/tex]
Where, r is the radius.
Putting [tex]r=8[/tex], we get
[tex]V_2=\dfrac{2}{3}\pi (8)^3[/tex]
[tex]V_2=\dfrac{1024}{3}\pi [/tex]
[tex]V_2\approx 341.3\pi [/tex]
Now, the volume of the composite figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=320\pi +341.3\pi[/tex]
[tex]V=661.3\pi[/tex]
The volume of the composite figure is 661.3π cm³.
The curved surface area of a cone is:
[tex]A_1=\pi r\sqrt{h^2+r^2}[/tex]
Where, r is the radius and h is the height of the cone.
Putting [tex]r=8,h=15[/tex] in the above formula, we get
[tex]A_1=\pi (8)\sqrt{(15)^2+(8)^2}[/tex]
[tex]A_1=\pi (8)\sqrt{289}[/tex]
[tex]A_1=\pi (8)(17)[/tex]
[tex]A_1=136 \pi [/tex]
The curved surface area of the hemisphere is:
[tex]A_2=2\pi r^2[/tex]
Where, r is the radius.
Putting [tex]r=8[/tex], we get
[tex]A_2=2\pi (8)^2[/tex]
[tex]A_2=2\pi (64)[/tex]
[tex]A_2=128\pi [/tex]
Total surface area of the composite figure is:
[tex]A=A_1+A_2[/tex]
[tex]A=136\pi +128\pi[/tex]
[tex]A=264\pi[/tex]
The total surface area of the composite figure is 264π cm².
Therefore, the correct option is A.

Answer:
see explanation
Step-by-step explanation:
(a)
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for B
∠ B = 180° - (90 + 63)° = 180° - 153° = 27°
(b)
Using the sine ratio in the right triangle
sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )
x × sin63° = 15 ( divide both sides by sin63° )
x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )
(c)
Using the tangent ratio in the right triangle
tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )
y × tan63° = 15 ( divide both sides by tan63° )
y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )

Identify a function rule for the following ordered pairs (0, -1), (2, 3), (3, 8), (4, 15)
A) y=x^2
B) y=x-1
C) y=x²-1
D) y=2x-1
Answer:
C
Step-by-step explanation:
Looking at the first point we know that it can't be A
Then we can easily see that the rate of change is not level (which means it isn't linear)
this leaves option C
Another way to solve this is just by plugging in points
for example for C
(4,15)
15=4^2-1
15=15

4) In how many ways can 6 players be assigned to 6 positions on a baseball team, assuming that any
player can play any position?
A) 30 ways
B) 720 ways
C) 1440 ways
D) 360 ways
Answer:
B. 720 ways
Step-by-step explanation:
To solve you would multiple 6x5x4x3x2x1 .
The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.
Given that,
Number of players = 6
Assigned position on a baseball = 6
We have to determine,
In how many ways can 6 players be assigned to 6 positions on a baseball team.
According to the question,
To solve this problem assuming that any player can play any position.
The formula to find [tex]^nP_r[/tex] is given by:
[tex]^np_r[/tex] is the permutation of arrangement of 'r' objects from a set of 'n' objects, into an order or sequence.
The formula to find permutation is:
[tex]^np_r = \frac{n!}{(n-r)!}[/tex]
Where, n = 6 and r = 6
Therefore,
[tex]^6p_6 = \frac{6!}{(6-6)!} \\[/tex]
[tex]= \frac{6\times5\times 4 \times 3 \times 2 \times 1}{0!} \\\\= \frac{720}{1} \\\\= 720 \ ways[/tex]
Hence, The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.

Hi there!
A function is a set of ordered pairs that do not have same x-values.
In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.
From the question above, you notice that two of the choices have same x-values and others don't have.
The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.
Any questions can be asked through comment.
Furthermore, a function is also a relation but a relation isn't always a function.

The graph shown below expresses a radical function that can be written in the form f(x) = a * (x + k) ^ (1 / n) + c does the graph tell you about the value of k in this function ? A. k equals zero.
B. k is less than zero.
C. k is greater than zero.
D. It is not possible to tell whether k is greater than or less than zero.
Answer:
C
Step-by-step explanation:
Just took the quiz
Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.
What is the value of k?We have a c value of -1 which is where the y axis is intercepted.
We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.
The only logical conclusion therefore, is that k is greater than zero.

A rental company charges $19 plus $10 per hour to rent a laptop . rented a for 8 hours. Write an expression to show how to calculate the total amount paid.
Answer:
Step-by-step explanation:
The cost is going to be 19 dollars before you even plug it in. You won't be charged 19 again while you are on this visit.
C = 19 + h*10
If you are on the computer for 8 hours then
C = 19 + 8*10
C = 19 + 80
C = 99
x+4/9=3/4 what is x?
Answer:
11/36
Step-by-step explanation:
To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.
