Question

What is the formula to find the curved surface area of cylinder​

Answer 1

Step-by-step explanation:

The radius 'r' of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

Answer 2

Answer:

$curved \: surface \: area \: = 2\pi r h$
