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.

Curved surface area of cylinder 88 cm² and height h = 14 cm
Let, the radius of base of cylinder = r cm
Curved surface area of cylinder = 2πrh
⇒ 88 = 2 × 22/7 × r × 14 ⇒ 88 = 88r ⇒ r = 1 cm
Hence, the diameter of base of cylinder = 2r = 2 × 1 = 2 cm.
