Question

Volume of a cylinder of height 3 cm is a 48π. Radius of the cylinder is ______.

Options

• 48 cm

• 16 cm

• 4 cm

• 24 cm

Answer 1

Volume of a cylinder of height 3 cm is a 48π. Radius of the cylinder is 4 cm.

Explanation:

Given Height of cylinder h = 3 cm

Volume of cylinder V = 48π

Let Radius of cylinder = r

V = πr²h

48π = πr² × 3

r² = `48/3`

= 16

r = `sqrt(16)`

= 4 cm
