Question

What is the volume of the cone?

A 72 pi cm^3
B 432 pi cm^3
C 288 pi cm^3
D 144 pi cm^3

Answer 1

Data:
r (radius) = 6 cm
h (height) = 12 cm
V (volume)= ?

Formula:

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

Solving:

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

`V = ( \pi * 6^2 * 12)/(3)`

`V = ( \pi *36*12)/(3)`

`V = (432 \pi )/(3)`

`\boxed{\boxed{V = 144 \pi cm^3}}\end{array}}\qquad\quad\checkmark`

Answer:
D 144 pi cm^3
