sorry Sravan ​

Answer 1

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. Let the radius of the base of the cylinder be r cm. Hence, the diameter of the base of the cylinder is 2 cm.

Flw me if you like my answer!!

Answer 2

Answer: 2 cm is the answer

Diameter = 2 × radius

Height of the cylinder, h = 14 cm

CSA of the cylinder = 88 cm²

2 π r h = 88 cm²

2 × 22/7 × r × 14 cm = 88 cm²

r = (88 cm² × 7) / (2 × 22 × 14) cm

= 1 cm

Diameter = 2 × radius

= 2 × 1 cm

= 2 cm

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