Write C++ code for the following programming exercises. (All inputs must be done in main(), and all four functions must be called from main()) 

 

Unfortunately I can't use more "advanced" coding techniques. I have to use functions, so I've included a sample of what the code should look similar to. I'm stuck on this and any help is much appreciated.

The following formula gives the distance between two points, (x1, Y1) and (x2, y2) in the Cartesian plane: 11. V(x2 – x1 )² + (y2 – yı)? Given the center and a point on the circle, you can use this formula to find the radius of the circle. Write a program that prompts the user to enter the center and a point on the circle. The program should then output the circle's radius, diameter, circumference, and area. Your pro- gram must have at least the following functions: distance: This function takes as its parameters four numbers that rep- resent two points in the plane and returns the distance between them. a. radius: This function takes as its parameters four numbers that represent the center and a point on the circle, calls the function distance to find the radius of the circle, and returns the circle's radius. b. circumference: This function takes as its parameter a number that represents the radius of the circle and returns the circle's cir- cumference. (If r is the radius, the circumference is 2tr.) C. area: This function takes as its parameter a number that repre- sents the radius of the circle and returns the circle's area. (If r is the radius, the area is Tr².) d. Assume that t = 3.1416.
