Question

The volume of a cone with a height of 6 cm is 8 PI cubic centimeters. Which expression can be used to find r, the radius of the

base of the cone?

Answer 1

The correct option is D.

8π = 1/3 * π * (r)² * 6

Explanation:

First of all to solve this problem we have to know the formula to calculate the volume of a cone

v = volume = 8π

r = radius

h = height = 6cm

π = pi

v = 1/3 * π * r² * h

we replace with the known values

8π = 1/3 * π * (r)² * 6

If we look at the options, the correct option is D.
