Question

Find The curved surface area of cylindri-
cal tank is 1,056m2. fits height is 12
find the radius.​
help me

Answer 1

Curved surface area of cylinder = 2*pi*r*h

1056 = 2* 22/7 * r * 12

r = 14 m

Therefore radius of cylinder is 14 m

Answer 2

Given :

✰ C.S.A of cylinder = 1056m²

✰ Height of cylinder = 12m

To Find :

✰ Radius

Solution :

✰ In the question Curved Surface area of cylinder and height is given. We will use the formula 2πrh, where h is Height and r is radius and put the values if height and curved Surface Area we can easily find the curved Surface Area of Cylinder.

C.S.A of cylinder = 2πrh

→ 1056 = 2 × 22/7 × r × 13

→ 1056 = 44/7 × 4 × r × 12

→ 1056/12 = 44/7 × r

→ 88 = 44/7 × r

→ r = 44/88 × 7

→ r = 14cm

∴ Radius of cylinder is 14cm.
