Exercise: Write a Python program which accepts the radius of a circle from the user and compute the area.

Python: Area of a Circle

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.

Python: Area of a circle

Sample Solution:-

Python Code:

from math import pi
r = float(input ("Input the radius of the circle : "))
print ("The area of the circle with radius " + str(r) + " is: " + str(pi * r**2))

Sample Output:

Input the radius of the circle : 1.1                                                                          
The area of the circle with radius 1.1 is: 3.8013271108436504
