Question

arera of circle and circumferance

Answer 1

Area: r² * Pi

Circumference: 2 * r * Pi

Now, that we've cleared the mathematics, give your best try to implement the code on whatever programming language you need to use.

Share your code if you'd like someone to review it.

Good luck!

Answer 2

#include<iostream>

using namespace std;

int main(){

int r;

cin >>r;

cout<<"Enter value of r"<<endl;

cout<<"the area of circle is  "<<r²*3.14;

cout<<"the curcumference is "<<2*r*3.14;

return 0;

}

Answer 3

Area = pi*r^2

where r is the radius

Circumference = pi*d

where d is the diameter

Answer 4

//BY MEDA HEMAL
#include<stdio.h>
int main()
{
    int rad;
    float PI=3.14,area,ci;
    printf("Enter radius :");
    scanf("%d",&rad);
    area = PI * rad * rad;
    printf("Area:%f\n",area);
    ci=2 * PI * rad;
    printf("Circumference:%f\n",ci);
    printf("by MEDA HEMAL");
}
