#Calculating the area of a circle

#Importing math
import math

#Getting radius from the user
sRadius = input("Please enter the radius of a circle: ")

#Casting to type integer
iRadius = int(sRadius)

#Calculating the area of the circle
fArea = math.pi * (iRadius**2)
#fArea = math.pi * math.pow(iRadius, 2)

#Printing the result
print ("The circle's area is: ", fArea)
