Q3 of 45 Page 11

The curved surface area of a cylindrical road is 132 cm2. Find its length if the radius is 0.35 cm.

Given: CSA of cylinder = 132 cm2


Radius of cylinder = 0.35 cm


To find: The length of cylinder


Formula Used:


CSA of cylinder = 2πrh


Explanation:


Let length of road = h cm


So, for the given values,


2πrh=132




Hence length of road is 60 cm.
