Question

find the curved surface area of a cylinder given its base circumference is 36 cm and its height is 4 cm​

Answer 1

Circumference of base of cylinder 36 cm

2πr = 36 cm

Height, h = 4cm

C.S.A. of cylinder = 2πr h

C.S.A. of cylinder = 36 × 4 = 144cm²

Answer 2

Circumference of base of cylinder 36 cm

2πr = 36 cm

Height, h = 4cm

C.S.A. of cylinder = 2πr h

C.S.A. of cylinder = 36 × 4 = 144cm²
