Question

A rectangular sheet of paper of dimension 25cm×22cm is rolled along its width to form a cylinder find the volume of cylinder so formed​

Answer 1

Answer:

Length of paper=.circumference of

cylinder

22=2πr

r=22/2π = 22x7/2x22=3.5 cm

h=25cm

vol of cylinder = πr 2h

=22/7. x3.5^2 x 25=962.5cm3

Answer 2

Answer:

Step-by-step explanation:

In the cylinder formed,

Height = 25cm

Circumfrence = 2πr = 22 cm

2×22/7×r = 22

r = 22×7/2×22

r = 7/2 cm

Volume = πr^2h

22/7 ×7/2 ×7/2 × 25

962.5
