QUESTION-13: Write a C Program that calculates the volume of a cube using one function. The function named calculate receives the side of a cube, computes, and returns its volume. In the main program, input the side of a cube from the user, call the function calculate and output the volume. Hint: Volume of a cube = q Sample Run: Enter side: 3 The volume is 27 Cube QUESTION-14: Write a C program that calculates the slope of a line. You are required to write a function called slop which takes two coefficients as input parameters (a and b) of and outputs the slope of the line inside the function. Remember: The slope of the line defined by the linear equation ax +by+c= 0 is: 6. a Sample Run: Enter the value of a: 3 Enter the value of b: 4 Enter the value of c: 15 The slope of the line is -0.75 4
