Question

A rectangular piece of paper 22 cm x 4 cm is folded without overlapping to make a cylinder
of height 4 cm. Find the volume of the cylinder.​

Answer 1

Answer:

154cm³

Step-by-step explanation:

circumstances of bottom circle of cylinder=22cm

so, 22=2πr

22=2×22/7×r

22×7/22×2=r

7/2=r

h=4cm (given)

volume of cylinder=πr²h

=22/7×7/2×7/2×4

=22×7

=154cm³
