The curved surface area of a right circular cylinder of height 14 cm is 88 cm^2. Find the diameter of the base of the cylinder.
Let r be the radius of the cylinder.
Here, height (h) = 14 cm and curved surface area = 88 cm2
Curved surface area of a cylinder = 2πrh
⇒ 2πrh = 88
⇒ 2 x 227 x r x 14 = 88
⇒ r = 88×7/2×22×14 = 1 cm
∴ Diameter = 2 x r = (2 x 1) cm = 2 cm

Given Curved Surface Area = 88cm^2.
2pirh = 88
2 * 22/7 * r * 14 = 88
2 * 22 * 2 * r = 88
88r = 88
r = 1.
We know that d = 2r = 2 * 1 = 2cm.
Base of cylinder = 2 cm.
Hope this helps! :)
