Question

The curved area of a right circular of height 14 cm in 88 cm2. find the diameter of the base of the cylinder.

Answer 1

Given h = 14cm.

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! :)            

Answer 2

Question :-

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.

Answer :-

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
