The curved surface area of a right circular cylinder of height 14 cm is 88 cm2. Find the diameter of the base of the cylinder. (Assume π =22/7 )

Solution:

Height of cylinder, h = 14cm

Let the diameter of the cylinder be d

Curved surface area of cylinder = 88 cm2

We know that, formula to find Curved surface area of cylinder is 2πrh.

So 2πrh =88 cm2 (r is the radius of the base of the cylinder)

2×(22/7)×r×14 = 88 cm2

2r = 2 cm

d =2 cm

Therefore, the diameter of the base of the cylinder is 2 cm.
