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

Answer:

The height of cylinder is 10 meters.

Step-by-step 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

$44 = 2 * \frac{22}{7} * 0.7 *h\\44 * \frac{7}{22} = 1.4h\\14 = 1.4h\\h=\frac{14}{1.4}\\h=10 m$

Hence,

The height of cylinder is 10 meters.
