Question

The volume of a cone is 50 pi cubic feet. Its height is 6 feet. In feet, what is the radius of the cone? Round the answer to the nearest tenth.

Answer 1

Answer:

The Answer is actually 8.9 ft

Answer 2

Answer:

The radius of the cone is $5\ ft$

Step-by-step explanation:

we know that

The volume of a cone is equal to

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

In this problem we have

$V=50\pi\ ft^{3}$

$h=6\ ft$

substitute in the formula and solve for r

$50\pi=\frac{1}{3}\pi r^{2}(6)$

Simplify

$25=r^{2}$

square root both sides

$r=5\ ft$
