Calculate The Area of a Circle and Circumference of a Circle in c, c++, python

 Find Area of a Circle and Circumference of a Circle

1: Python

radius=float(input("ENTER THE RADIUS = "))

area=(22/7.0)*radius *radius

circumference=2*(22/7.0)*radius

print("AREA OF CIRCLE")

print(area)

print("--------")

print("CIRCUMFERENCE OF CIRCLE")

print(circumference)

2: C++

#include<iostream>

using namespace std;

int main()

{

float radius, area, circumference ;

cout<<"ENTER THE RADIUS =";

cin>>radius;

area=(22/7.0)*radius *radius;

 circumference=2*(22/7.0)*radius ;

cout<<"\n\tAREA OF CIRCLE = "<<area;

cout<<"\n\tCIRCUMFERENCE OF CIRCLE= "<<circumference ;

    

    return 0;

}

3:C

#include<stdio.h>

int main()

{

float radius, area,circumference;

    printf("ENTER THE RADIUS = ");

    scanf("%f", &radius);

    area=(22/7.0)*radius *radius;

    circumference=2*(22/7.0)*radius ;

    printf("\n\tAREA OF CIRCLE = %0.3f", area);

    printf("\n\tCIRCUMFERENCE OF CIRCLE = %0.3f", circumference);

    return 0;

}
