A cylinder has a height of 15 cm and the radius of its base is 5 cm. What is the area of its curved surface?

(Take π = 3.14)

Let the base radius be ‘r’ and height be ‘h’ and diameter be ‘d’

⇒ Given that ∴ r = 5 cm

and h = 15 cm

⇒ Curved surface area A= Circumference× height
A=2πr× h

A=2π× 5× 15

Total curved surface area

Ans. 471 sq cm
