Question

find the curved surface area of a cylinder whose volume is 500 cm cube and the radius is 10 cm

Answer 1

Sol.) • Given,

Radius of a cylinder = 10 cm

Volume of a cylinder = 500 cm³.

• To find,

Curved Surface Area (CSA) of a cylinder.

• Calculation,

Volume of a cylinder = πr²h

500 = 22/7 x (10)² x h

(500 x 7)/(22 x 100) = h

h = 35/22 cm

CSA of a cylinder = 2πrh

= 2 x 22/7 x 10 x 35/22

= 2 x 10 x 5

= 100 cm² Ans.
