Answer 3

Plug the numbers into the volume formula:

V = 1/3 * pi * r^2 * h = 1/3 * 3.14 * (3)^2 * 3 = ?

Answer 4

i got B

Answer 5

pi is missing from the volume formula in the problem as you typed it. B is not the answer.

Answer 6

Cone Volume = (1/3)(pi)r2h

Answer 7

oh its A

Answer 8

No. I showed the work above. Just use your calculator to multiply:
1/3 * 3.14 * (3)^2 * 3

Answer 9

C

Answer 10

yes.
