Question

the volume of a cone is 120 cubic centimeters. the height of the cone is 4.5 centimeters. determine the radius of a cone

Answer 1

given:

`v = 120 \: {cm}^(3)`

`h = 4.5 \: cm`

to find:

the radius of the cone.

solution:

`r = \sqrt{3 (v)/(\pi \: h) }`

`r = \sqrt{3 * (120)/(\pi * 4.5) }`

`r = 5.04627 \: cm`

`r = 5.05 \: cm`

hence, the radius of the given cone is 5.05 centimeters.
