Python - Usage imports

Define a function called `calc` which takes one parameter. The parameter 'c' is an integer which is the circumference of the circle. The function definition code stub is given in the editor. Find the radius and Area of the circle using math module based on condition given below:

 

• Formula for
  • Radius: 
  • Area:  

• Return both Radius and Area. 
  • The values must be rounded off to 2 positions.

Constraints

• input must be an integer.

Input Format Format for Custom Testing

 

• In the first line c given.

Sample Case 0

 

Sample Input

STDIN      Function
-----      --------
8       →  c = 8

Sample Output

(1.27, 5.09)  

Explanation

• With 8 as input, Radius and Area are calculated and returned
