The following formula can be used to describe the dimensions of a loading ramp:

Question

sin( ) = h

where is the incline angle of the ramp, h is the height of the ramp, and l is the

length of the ramp. Write a program that calculates the needed length of a ramp

given a desired incline and height. For example, given an incline of 9.5 degrees

and a height of 0.5 m, a ramp needs to be 3.03 m in length. The program should

prompt the user for the needed values and calculate and report the required

length. The program should make use of the math library for the sin() function,

and should use the macro M_PI for the value of to convert degrees to radians

(radians = degrees ×

180 ).

# include<iostream.>

# include<math.h>

#include<conio.h>

float radians,degrees,h,l;

//define PI value

#define PI 3.14

//macro which calculates the angle in radians

#define M_PI ((radians=degrees*PI)/180)

void main()

{

//enter the degrees

cout<<"Enter the sign value in degrees"<<endl;

cin>>degrees;

//enter height h as 0.5m

cout<<"Enter the height in metre"<<endl;

cin>>h;

//enter length l as 3.03m

cout<<"enter the length in metre"<<end;

cin>>l;

//formula to calculate the dimensions i.e report required for length

sin(M_PI)=hl;

//print the result

cout<<"The report required for length is "<<sin(M_PI)<<endl;

getch();
