Question

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

Answer 1

The volume of a cone can be found by using the equation V=(1/3)(pi*r^2*H). Given the information that H= 6cm and V= 8pi cm^3, the expression is 8pi=(1/3)(pi*r^2*6). (The second picture.)

Answer 2

For this case we have by definition, that the volume of a cone is given by "

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

Where:

h: It's the height

r: It is the cone radius

They tell us as data that the volume is 8
`\pi`and the height is 6 cm, we must find an expression that allows to clear the radius, then:
`8 \pi = \frac {1} {3} \pi * r ^ 2 * 6`
