Question

The area of the base of a circular cylinder is 35cm^2 and its height 12cm. What will be its volume?

Answer 1

volume=base area *height
35*12
420cm²

Answer 2

Given :

The area of the base of a circular cylinder is 35cm^2 and its height 12cm.

To Find :

What will be its volume?

Solution:

Formula of area of circular base =$\pi r^2$

We are given that area of base is 35 sq.cm.

So,$\pi r^2 = 35$

Height of cylinder = 12 cm

Volume of cylinder = $\pi r^2 h = 35 \times 12= 420 cm^3$

Hence The volume of cylinder is 420 cubic cm.
