Question

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

Answer 1

Answer ⤵️

•Given:-

● Circumference of cylinder=22 cm

● Height of cylinder = 10 cm

•Solution:-

Circumference = 2πr

=> 2πr = 22

=> 2 × 3.1416 × r = 22

=> 6.2832 × r = 22

=> r = 22/6.2832

=> r = 3.5 m

\rule{300}{2}

Volume of cylinder = πr^2h

=> Volume = 3.1416 × (3.5)^2 × 10

=> Volume = 3.1416 × 12.25 × 10 m^3

=> Volume = 384.85 m^3
