The radius of a right circular cylinder is five times of its height. If the height of the cylinder is 3.5 cm, then what is the volume of cylinder?

3368.75 cm³

We know that,

Volume of a cylinder = πr²h

The radius of a right circular cylinder = five times its height.

The height of the cylinder = 3.5 cm

The radius of the cylinder = 3.5 × 5 = 17.5

Now,

Volume = π × 17.5² × 3.5

= \(\frac{22}{7}\) × 17.5 × 17.5 × 3.5 = 22 × 2.5 × 17.5 × 3.5 = 3368.75
