Question

if the lateral surface area of a cylinder of radius 13 cm and height 21 cm to be covered with paper the area of paper require is​

Answer 1

Given,

The radius of the cylinder = 13cm

The height of the cylinder = 21cm

To find,

The lateral surface area of the given cylinder.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we have to apply the lateral surface area formula for cylinder.

Lateral surface area of the given cylinder :

= 2 × 22/7 × 21 × 13

= 1716 cm²

Hence, 1716 cm² paper is required.
