Question

The volume of a cylinder is 54 cm' and its height is 16 cm, what will be its curved
surface area?
​

Answer 1

Answer:

volume = 5544 cm³kyu

height = 16 cm

volume of cylinder = πr²h

5544 = 22/7 x r² x h

5544 x 7/22 x 1/16 = r²

441/4 = r²

r = √441/4

r = 21/2 cm (10.5 cm)

curved surface area = 2πrh

= 2 x 22/7 x 21/2 x 16

= 22 x 3 x 16

= 1056 cm²².
