Q. 64.4( 195 Votes )

Curved surface area of a right circular cylinder is 4.4 m2. If the radius of the base of the cylinder is 0.7 m, find its height

Answer :

To Find: Height of the cylinder

Given: Curved surface area of cylinder = 4.4 mand radius of cylinder = 0.7 m

Concept Used:

Curved Surface Area of cylinder = 2πrh

where, r = radius of base of cylinder and h = height of cylinder

Explanation:


Let the height of the circular cylinder be h

2πrh = 4.4 m2               

(2 × 22/7 × 0.7 × h) m2 = 4.4 m2

4.4 h = 4.4 m2

h = 1 m


Therefore, the height of the cylinder is 1 m
