Question

The height of a cylinder is 11cm and its curved surface area is 968 sq. cm. find the radius of cylinder.

Answer 1

Answer:

csa of cylinder is 2 pie rh

radius = x

height = 11

csa = 2×22/7×x×11

968 = 44×11×x/7

88 = 44x/7

x/7 = 2

x = 14

Answer 2

The radius of the cylinder is 14 cm.

Step-by-step explanation:

Given: Height of cylinder 'H' = 11 cm

Curved Surface Area 'CSA' = 968 sq. cm

To Find: Radius 'R' of the cylinder

Solution:

• Finding radius of the cylinder

We know that the CSA of the cylinder is CSA = 2πRH. Therefore, substituting values and calculating, we get,

⇒ 968 = 2π × R × 11

$\Rightarrow R = \frac{968 \times 7}{2 \times 22 \times 11} = 14 cm$

Hence, the radius of the cylinder is 14 cm.
