Question

A rectangular paper of size 22cm *14cm is rolled to form a cylinder of height 14cm .Find the volume of the cylinder.

Answer 1

Given,

h = 14 cm

2πr = 22 cm

=> 2 × 22/7 × r = 22

=> 44/7 × r = 22

=> r = 22 × 7/44

=> r = 7/2

.°. r = 7/2 cm

Volume

= πr²h

= 22/7 × 7/2 × 14

= 154 cm³

Answer 2

Answer:

2148 cube cm

radius =14/2 = 7cm

height = 14cm

Volume of cylinder is pie × radius square × height

22/7 × 7 × 7 ×14=2148
