Write a program to find and display the volume of a sphere, and a cylinder with the following formulas:
volume of a sphere=4/3πr2
volume of a cylinder=πr2h
Answers
Answer:
Explanation:
A) Answer-
#include <stdio.h>
float myradius; /* radius of the sphere */
float myvolume; /* volume of the sphere (to be computed) */
char line_text[50]; /* a line from the keyboard */
/* the value of pi to 50 places, from wikipedia */
const float PI = 3.14159265358979323846264338327950288419716939937510;
int main() {
printf("Input the radius of the sphere : ");
fgets(line_text, sizeof(line_text), stdin);
sscanf(line_text, "%f", &myradius);
myvolume = (4.0 / 3.0) * PI * (myradius * myradius * myradius); /* volumn=(4/3) * pi * r^3*/
printf("The volume of sphere is %f.\n", myvolume);
return(0);
}
Output-
Input the radius of the sphere : 2.56
The volume of sphere is 70.276237.
B) Answer-
int main()
{
float vol,r,h;
printf("enter radius: ");
scanf("%f",&r);
printf("enter height: ");
scanf("%f",&h);
vol=(22*r*r*h)/7;
printf("VOC: %f\n",vol);
return 0;
}
output:
enter radius: 7
enter height: 7
VOC: 1078.000000
