Question

A rectangular paper is 22 cm long and 10 cm wide . It is folded without overlapping to make a cylinder of height 10 cm . Find the volume of the cylinder.

Answer 1

Answer:

if we roll this rectangular piece height is 22 cms and the circumference of base is 10cm

so,

2πr=10

2×22/7×r=10

r=10×7/44

r=5×7/22

volume of cylinder =π×r×r×h

=22/7×35/22×35/22×22

=5×35cm^3

=175cm^3
