Question

What is the volume of the cone with radius 4 ft and height 10 ft? Round to the nearest cubic foot.

A) 126 ft3


B) 200 ft3


C) 251 ft3


D) 168 ft3

Answer 1

Answer:

D) 168 ft3

Step-by-step explanation:

The formula to find the volume of a cone is V=π$r^{2}$$\frac{h}{3}$.

We need to plug in the radius, 4, and the height, 10, into this equation.

V=π$(4)^{2}$$\frac{10}{3}$

V=π16$\frac{10}{3}$

V=π53.33

V=167.55

If we round up to the nearest whole number, we get 168 $ft^{3}$. Therefore, the correct answer is D) 168 ft3.
