Question

The area of the base of a right circular cylinder is 154cm and its height is 8 cm. find the curved surface area of cyclinder.​

Answer 1

Step-by-step explanation:

Curved surface area= 2πrh

Area of base= πr^2

154= π x r^2

r= 7cm

Curved surface area= 2πrh

C.S.A= 2 x π x 7 x 8

C.S.A= 351.92 cm^2
