Question

A rectangular sheet of paper 44cm*33cm is rolled along its length frist, then along its breadth and cylinders are formed. The ratio of volume is..

Answer 1

Answer:

Step-by-step explanation:

The height of cylinder if it is rolled along it's length =33cm

Circumference of base =44cm

Therefore,radius of base =44÷2π=7cm

Therefore,volume in first case =πr^2h = 22÷7×7×7×33=5082cm^3

In the second case

Height of cylinder=44cm

Circumference of base=33cm

•

• • radius = 33÷2π=5.25cm

VOLUME=πr^2h=

3811.5cn^3

Ratio of volumes= 5082÷3811.5= 4:3
