4.20 Lateral Surface Area of a Cylinder



Example:
Find the lateral surface area of right circular cylinder, if its base has a radius of 3.5cm. and its height is 10cm.
Solution:
Formula for lateral surface area of a curved surface = 2* pi * r * h.
Here given that, r = 3.5cm. and h = 10cm.
Curved surface area = 2 * 22/7 * 3.5 * 10
= 220 Sq. cm.
