Write a function that calculates the area of, a circle when its circumference, c, is given . This function should call a second function that returns the radius, r, of the circle, given c. The relevant formulas are r= c/2π and a= πr2.

Written in Python

def Areas(radius):

    pi = 22.0/7.0

    Area = pi * radius**2

    print("The area is: "+str(Area))

def Radius(circum):

    pi = 22.0/7.0

    radius = circum/(2 * pi)

    Areas(radius)

Explanation:

The first function is defined as thus: The parameter in the bracket, radius, is returned from the second function

def Areas(radius):

This line initializes pi to 22/7

    pi = 22.0/7.0

This line calculates the area of the circle

    Area = pi * radius**2

This line prints the area of the circle

    print("The area is: "+str(Area))

The second function is defined as thus: It gets the circumference from the main and returns the radius to the function defined above

def Radius(circum):

This line initializes pi to 22/7

    pi = 22.0/7.0

This line calculates the radius of the circle

    radius = circum/(2 * pi)

This line returns the radius of the first function

    Areas(radius)

To return the proper result, the Radius function must first be called using the following syntax.

Radius(any digit)

Example

Radius(60)
