Question

A rectangular piece of paper 22cm by 8cm is folded without overlapping to make cylinder of height 8cm.Find the volume of cylinder?

Answer 1

Answer:

In this question , Height of the cylinder = 6 cm.

And , Circumference of the base = 22 cm

So, 2*22/7*r = 22.

i.e. r = 7/2 cm.

Apply the formula of volume of cylinder = 22/7*r^2*h

i.e. 22/7 * 7/2 * 7/2* 6 cubic cm = 231 cubic cm
