Question

A rectangular metal sheet of length 44 cm and breadth 11 cm is folded along its length to form a cylinder. Find its volume.

Answer 1

The volume of the cylinder is 2772 cm^3.

Explanation

Let the radius be = r

we know that the length of the sheet = circumference of the circle

Height of the cylinder = 18 cm

44 = 2r

2 x 22/7 r = 44

r = (44 x 7) / (22 x 2)

r = 7 cm

Volume of cylinder = r^2 .h

=22/7 * 7*7 * 18

= 2772 cm^3

The volume of the cylinder is 2772 cm^3.
