Question

The volume of a cylinder whose radius r is equal to its height is ______.

Options

• `1/4 pir^3`

• `(pir^3)/32`

• `pir^3`

• `r^3/8`

Answer 1

The volume of a cylinder whose radius r is equal to its height is πr³.

Explanation:

Given, r = h
Then, volume of cylinder = πr²h = πr²r = πr³
