Required Answer:-

Question:

• Write a program to calculate and print the perimeter and area of a circle in Python.

Solution:

Sample program in Python.

import math

r=float(input("Enter radius: "))

c=2*math.pi*r

a=math.pi*r*r

print("Circumference: ",c)

print("Area: ",a)

Explanation:

• Area and circumference is given by the formula - A = πr² and P = 2πr. To use the value of π, we have to import the math module. From that, we can use the value of pi. math.pi contains the value of pi. In this way, we can calculate the area and circumference of the circle.
