This is a C Program to find the volume and surface area of cone.

This C Program calculates the volume and surface area of cone.

This program is used to find the the volume and surface area of cone. The formula used in this program are Surface_area = Pi * r * (r + sqrt(r2 + h2)), Volume = 1 / 3 * Pi * r2 * h where r is the radius and h is the height of the cone & Pi = 22/7.

Here is source code of the C Program to Find the volume and surface area of cone. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

/* * C Program to Find the volume and surface area of cone */ #include <stdio.h> #include <math.h> int main() { float radius, height; float surface_area, volume; printf("Enter value of radius and height of a cone :\n "); scanf("%f%f", &radius, &height); surface_area = (22 / 7) * radius * (radius + sqrt(radius * radius + height * height)); volume = (1.0/3) * (22 / 7) * radius * radius * height; printf("Surface area of cone is: %.3f", surface_area); printf("\n Volume of cone is : %.3f", volume); return 0; }

In this C program, library function defined in <math.h> header file is used to compute mathematical functions. We are reading the ‘radius’ and ‘height’ of a cone. To find the surface area and the volume, the following formulas are used.

Surface area = 3.14 * radius * (radius + sqrt ((radius * radius) + (height * height)),

Volume = 1 / 3 * 3.14 * radius * radius * height.

Output: $ cc pgm31.c -lm $ a.out Enter value of radius and height of a cone : 6 9 Surface area of cone is: 302.700 Volume of cone is : 324.000
