Read the height and radius of a Cone from the user, and then calculate the surface area and volume of Cone.

Surface area of Cone:

To calculate the surface area of Cone (Right Circular Cone), the formula is:

Volume of Cone:

To calculate the volume of Cone (Right Circular Cone), the formula is:

Where,

• r : Radius of the Cone
• h : Height of the Cone

Program:

The source code to calculate the surface area, volume of the Cone is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.

// C program to find the surface Area and
// volume of Cone

#include <stdio.h>
#include <math.h>

int main()
{
    float height = 0;
    float radius = 0;

    float volume = 0;
    float area = 0;

    printf("Enter the height: ");
    scanf("%f", &height);

    printf("Enter the radius: ");
    scanf("%f", &radius);

    volume = (1.0 / 3) * (3.14) * radius * radius * height;
    area = (3.14) * radius * (radius + sqrt(radius * radius + height * height));

    printf("Volume of Cone 	    : %f\n", volume);
    printf("Surface area of Cone: %f\n", area);

    return 0;
}

Output:

RUN 1:
Enter the height: 12.3
Enter the radius: 4
Volume of Cone      : 205.984009
Surface area of Cone: 212.691849

RUN 2:
Enter the height: 1.2
Enter the radius: 3.4
Volume of Cone      : 14.519361
Surface area of Cone: 74.791267

RUN 3:
Enter the height: 10
Enter the radius: 6
Volume of Cone      : 376.799988
Surface area of Cone: 332.750275

Explanation:

Read the value of height and radius from the user. Then we calculated the surface area and volume of Cone using standard formulas.
