Question

Find the curved surface area of a cylinder 10 cm dia and 20 cm height

Answer 1

Answer: 628.57 cm^2

Step-by-step explanation:

Radius = Diameter / 2 = 10 / 2 = 5 cm.

CSA of cylinder = 2πrh

                            = 2 * 22 / 7 * 5 * 20

                            = 4400 / 7

                            = 628.57 cm^2
