Question

What is the exact volume of a cone with a height of 15 cm and a radius of 5 cm?
V=1/3πR2h

Answer 1

The exact volume is
`V=125\pi\ cm^(3)`

Explanation:

we know that

The volume of a cone is equal to

`V=(1)/(3)\pi r^(2)h`

where

r is the radius

h is the height

we have

`r=5\ cm`

`h=15\ cm`

substitute

`V=(1)/(3)\pi (5)^(2)(15)`

`V=125\pi\ cm^(3)`
