Write a function area_of_circle(r) which returns the area of a circle of radius r

As a refresher, the area of any circle is equal to the radius squared, multiplied by pi (where pi is 3.14159....).

Dont forget to include the math module, where pi is defined.

this is what i have so far kept getting error on line 8

import math

def area_of_circle(r):

# A=pir2

Area = math.pi * (r**2)

return Area

def main():

t = (int(input('radius')))

print(area_of_circle(t))

if _name_ == _'main'_

main():
