Program to find the surface area of the cylinder

Explanation

In this program, we have a cylinder with the given radius and height. We need to find its Surface area.

A cylinder is a three-dimensional geometrical figure/container with straight parallel sides and two circular cross-sections. So we have three surfaces of the cylinder.

The surface area of two circular cross-sections = 2( Π × r × r )

The surface area of parallel sides = Circumference times the height = 2 Π × r × h

Total Surface Area of Cylinder = 2( Π × r × r ) + 2 Π × r × h = 2 Π (r + h)

Formula

Surface Area of Cylinder = 2 Π  (r + h)
Here, r is the radius and h is the height of the cylinder.
	Π ( pi ) = 22/7 = 3.14

Algorithm

1. Define the values of radius and height.
2. Insert into given formula.
3. Print the Surface Area of Cylinder.
