C Program To Calculate Surface Area of Sphere

Given the value for radius of a Sphere, write a C program to calculate Surface Area of the Sphere.

Formula To Calculate Surface Area of Sphere

When radius value is known: Area = 4 * π * radius²,
When diameter value is known: Area = π * diameter²,
When volume value is known: Area = ³√(36 * π * Volume²).

where π (PI) is approximately equal to 3.14

Logic To Calculate Surface Area of Sphere

We ask the user to enter the value of radius of the sphere. We apply the formula:
Surface_ Area = 4 * PI * radius2
where π (PI) is approximately equal to 3.14

Expected Output for the Input

User Input:
Enter Radius of the Sphere
5

Output:
Surface Area of Sphere is 314.000000

Source Code: C Program To Calculate Surface Area of Sphere

#include<stdio.h>

int main()
{
    const float PI = 3.14;
          float r, area;

    printf("Enter Radius of the Sphere\n");
    scanf("%f", &r);

    area = ( 4 * PI * r * r );

    printf("Surface Area of Sphere is %f\n", area);

    return 0;
}

Output 1:
Enter Radius of the Sphere
2
Surface Area of Sphere is 50.240002

C Program To Calculate Volume of Sphere

Given the value for radius of a Sphere, write a C program to calculate volume of the Sphere.

Formula To Calculate Volume of Sphere

volume = ( 4 * PI * radius3 ) / 3.0;

OR

volume = ( 1.333 * PI * radius3 );

volume of sphere

where PI is approximately equal to 3.14;

Expected Output for the Input

User Input:
Enter Radius of the Sphere
5

Output:
Volume of Sphere is 523.333374

Logic To Calculate Volume of Sphere

We ask the user to enter value for radius of the Sphere. If user enters 5 inche. Then we use the formula to calculate the Volume of Sphere:

volume = ( 4 * PI * radius3 ) / 3.0;

User input:
radius = 5 inches;

PI value is approximately equal to 3.14;

volume = ( 4 * PI * radius3 ) / 3.0
volume = ( 4 * 3.24 * (5 inches)3) / 3.0
volume = ( ‭12.56‬ * 125 inches3 ) / 3.0
volume = ( ‭12.56‬ * 125 inches3 ) / 3.0
volume = ‭1,570‬ inches3 / 3.0
volume = ‭523.33 inches3
