Question

If the lateral surface of a cylinder is 94.2 cm² and its height is 5 cm, find:

(i) radius of its base

(ii) volume of the cylinder
[Use $\mathrm{\pi }$ = 3.14]

Answer 1

Given data is as follows:

Lateral Surface Area = 94.2 cm²

h = 5cm

We have to find:

(i) Radius of the base

(ii) Volume of the cylinder

(i) We know that,

Lateral Surface Area =

That is,

2πrh = 94.2

=94.2

=94.2

(ii) Volume of a cylinder =

=
