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

I have used python 3.7 compiler for debugging purpose.

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

Result:

Input the radius of the circle : 5

The area of the circle with radius 5.0 is : 78.53981633974483
