Question

.
The curved surface of cylinder is 484 cm^2 and height is 5.5 cm. Find its radius.​

Answer 1

radius= 14

Explanation:

curved surface area of cylinder = 484

height = 5.5

C.S.A = 2πrh

or, 484 = 2×22/7×r×5.5

or, 484×7 = 2×22/7×5.5×r

or, 3388 = 242×r

or, 3388/242 = r

or, 14 = r

Answer 2

r=14cm

Explanation:

Curved Surface area of a cylinder=484cm²

Height=5.5cm

r=?

Curved Surface Area=2πrh

484=2×3.142×r×5.5

484=34.56r

r=484/34.56

r=14cm
