Solution

Height (h) of cylinder = 14 cm

Let the diameter of the cylinder be d.

Curved surface area of cylinder = 88 cm2

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

⇒ πdh = 88 cm2 (d = 2r)

`rArr22/7xxd xx14cm = 88" cm"^2`

⇒ = 2 cm

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