Because PI is a static property of Math, you always use it as Math.PI, rather than as a property of a Math object you created.
Output will be :
The Approximate value of PI is: 3.141592653589793
The following example is the simple implementation of the formula : A = PI * R* R, where R is the radius of the circle and A is the area of the circle.
