Question

What is the volume of the cone to the nearest whole number?

A.) 100π ft^3

B.) 33π ft^3

C.) 60π ft^3

D.) 180π ft^3

Answer 1

I believe the answer to be C. 

Answer 2

Answer:

(A) $100{\pi}ft^3$.

Step-by-step explanation:

It is given from the figure that the radius of the cone is 5 feet and the height is 12 feet, then then volume of the cone is given as:

$V={\frac{1}{3}{\pi}r^2h$

Substituting the given values, we get

$V={\frac{1}{3}{\pi}(5)^2(12)$

$V={\frac{1}{3}{\pi}(25)(12)$

$V={\pi}(25)(4)$

$V=100{\pi}ft^3$

Thus, the volume of the cone is $100{\pi}ft^3$.

Hence, option (a) is correct.
