What is the exact volume of the cone?



A.


32π in3


B.


96π in3


C.


256π in3


D.


768π in3

Answer 1

Use the formula

V = (1/3)*pi*r^2*h

V = volume
r = radius
h = height

Answer 2

I am having trouble doing that

Answer 3

In this case,

r = 8
h = 12

Answer 4

8*12 ?

Answer 5

V = (1/3)*pi*r^2*h

V = (1/3)*pi*8^2*12

V = ???

Answer 6

I don't understand

Answer 7

what is 8^2

Answer 8

64

Answer 9

then multiply that with 1/3 and 12

Answer 10

768

Answer 11

that's too large

Answer 12

oh.. I did the wrong math... 96??

Answer 13

64*12 = ???

Answer 14

= 768

Answer 15

now you multiply that by 1/3

ie divide by 3

Answer 16

256

Answer 17

thank you

Answer 18

:)

Answer 19

good, so the final answer is \[\large 256\pi\]

you're welcome
