Sololearn don't accept my code

Question

Python Core
37.3 Practice
Circle Dimensions

You are given a program that takes the radius of a circle as the input.
Complete the code to calculate the circle's perimeter and output the result.
Remember, the perimeter of a circle = 2*pi*radius

from math import pi
radius = int(input())

def perim():
return 2*pi*radius

def area():
return pi*radius*radius

print("Perimeter:", round(perim(), 2))
print("Area:", round(area(), 2))

What is wrong?

Answer 1

You just have to print perimeter value

Don't print area

Your code is right but there is a problem in that practice.

When I had solved this problem then we had to print Perimeter as well as Area but I think Sololearn have changed something in test cases and in problem statement too.

Answer 2

This code is correct:

from math import pi
radius = int(input())

perimeter = 2 * pi * radius
print(round(perimeter, 2))

Answer 3

Hi!
There is no error found in your program. You're saying that they asked you to calculate the circle's perimeter only but you calculated its area additionally. I think this can be your problem. I mean try to print only its perimeter value as output.
Here it is what I mentioned above
print(round(area(),2))

Answer 4

Because I am not a pro member, ı dont see whole question. as far as i can understand the question, this is my solution:

from math import pi
def circle (a):
print("perimeter : ", 2*pi*a)
print("area : ", pi*(a**2))
circle(int(input("enter radius of the circle: ")))
