Exercise#1: The following formula gives the distance between two points (x1, yı) and (x2, y2) in the Cartesian plane:
Given the center and a point on circle, you can use this formula to find the radius of the circle. Write a C++ program that prompts the the user to enter the center and point on the circle. The program should then output the circle's radius, diameters, circumference, and area. Your program must have at least the following methods: findDistance: This mehod takes as its parameters 4 numbers that represent two points in the plane and returns the distance between them. findRadius: This mehod takes as its parameters 4 numbers that represent the center and a point on the circle, calls the method findDistance to find the radius of the circle, and returns the circle's radius. circumference: This mehod takes as its parameter a number that represents the radius of the circle and returns the circle's circumference. area: This mehod takes as as its parameter a number that represents the radius of the circle and returns the circle's area. .​
