#Try this

def calc(r):
import math
p=2*math.pi*r
return p
#print("to find p")
r=float(input())
a=calc(r)
print("p:",round(a, 2))

#It's not necessary to add extra things in the task

Answer 2

Ok , thanks Pąľľąvī and Simba 😁

Answer 3

the artist Recheck the link you've attached in the Question .

Answer 4

print("to find p")
r=float(input("Enter Radius :"))
a=calc(r)
print("p:",round(a, 2))

Answer 5

#use this short code

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

perim = 2*pi*radius

print(round(perim, 2))

Answer 6

Wait I will post question and my code

Answer 7

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

Sample Input
5

Sample Output
31.42

You need to import the pi constant from the math module to perform the calculation.

Answer 8

And output is 31.42 of the code but it gives error 😐
