3. Create a new Class and call it InputArea. Write a program that asks the user for the area (double) of a circle. Then calculate the radius (double) of the circle and print it out.  To find the radius of a circle use the formula Math.sqrt(area/Math.PI)

Sample Output:
This program calculate the radius of a circle with the given area
