Answer» Given :h = 14 cm, curved, surface area = 88 cm2, r = ? Curved surface area of the cylinder = 2πrh 88 = 2 × 22/ 7 × r × 14 88 = 44 × 2 × r r = 88/ 44 × 2 = 1 Hence, base diameter of the cylinder = 1 × 2cm = 2 cm Like if you find it useful

The curved surface area of a right circular cylinderof height 14 cm is 88 cm2. Find the diameter of thebase of the cylinder.

Answer»

Given :h = 14 cm, curved, surface area = 88 cm2, r = ?

Curved surface area of the cylinder = 2πrh

88 = 2 × 22/ 7 × r × 14

88 = 44 × 2 × r

r = 88/ 44 × 2 = 1

Hence, base diameter of the cylinder = 1 × 2cm = 2 cm
