Question

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

Answer 1

π = 22/7

Height (h) of cylinder = 14 cm

Let the diameter of the cylinder be d.

Curved surface area of cylinder = 88 cm²

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

⇒ πdh = 88 cm² (d = 2r)

⇒ 22/7 x d x 14cm = 88 cm²

⇒ d = 2cm

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