Question

The curved sulace of the pillar at the rate of 12,50 per m.

Curved surface area of a right circular cylinder is 44 m. If the radius of the base of the
cylinder is 0.7 m, find its height,​

Answer 1

The height of cylinder is 10 meters.

Explanation:

Given

Curved Surface Area = 44m^2

Radius = r = 0.7 m

The curved surface area of a cylinder is given by:

`CSA = 2\pi rh`

Putting the values we get

Pi can be taken as 22/7 or 3.14

We are taking 22/7 for the question

`44 = 2 * (22)/(7) * 0.7 *h\\44 * (7)/(22) = 1.4h\\14 = 1.4h\\h=(14)/(1.4)\\h=10 m`

Hence,

The height of cylinder is 10 meters.
