Question

Curved surface area of a right circular cylinder is 4.4 m². If the radius of the base of the cylinder is 0.7 m, find its height.

Answer 1

Given:

Radius of base of the cylinder `e_r = 0.7m`

Curved surface area of cylinder = `4.4m^2 = 2πrh`

Let h be the height of the cylinder

WKT,

`2πrh = 4.4m^2`

2 × 30.14 × 0.7 × h = 4.4

`(4.4)hm −  4.4m^2`

1 = hm

∴The height of the cylinder is 1m.
