C++ Program To Find Area And Circumference Of Circle

Circumference :-Circumference of circle is the distance around the circle. Calculate The Circumference of Circle By Given Formula

Circumference = 2*π*r 

Here PI (π) is a Greek Letter and r is a Radius (1/2 Of Diameter )

PI (π) = 3.141592653589793 Approx. It Is A Constant Value for more about Circumference Click Here
