diameter revolutions time
The diameter is expressed in inches as a floating point value. The revolutions is an integer value. The time is expressed in seconds as a floating point value. Input ends when the value of revolutions is 0 (zero).
Trip #N: distance MPH
Of course N should be replaced by the data set number, distance by the total distance in miles (accurate to 2 decimal places) and MPH by the speed in miles per hour (accurate to 2 decimal places). Your program should not generate any output for the ending case when revolutions is 0.
Constants
For p use the value: 3.1415927. There are 5280 feet in a mile. There are 12 inches in a foot. There are 60 minutes in an hour. There are 60 seconds in a minute. There are 201.168 meters in a furlong.
#include <stdio.h>
#define pi 3.1415927 int main()
{
double a,c;
int b,k=;
while(scanf("%lf %d %lf",&a,&b,&c),b)
{
printf("Trip #%d: ",k++);
printf("%.2lf %.2lf\n",*pi*a*b///,*pi*a*b*////c);
}
return ;
}
