#Ask the user for a radius of a circle
user_r­adius = input(­"What is a radius of a circle­?")

#Convert the given radius to a floating point
radius = float(­use­r_r­adius)

#Make a variable called pi
pi = float(­3.1415)

area = pi(rad­ius*2)

#Display the area of the circle to the user
print ("The area of the circle is", area)
