The following formula gives the distance between two points, (x1, y1) and (x2, y2) in the Cartesian plane: V(a2 - 1) + (v2 – y1)² 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. The formula for calculating the area of a circle is: A = Tr? The formula for calculating the perimeter of a circle is: C = 2r Your program must have at least the following functions: • calculateRadius: Receives the x-y coordinates of the center and point on the circle (as input by the user) and calculates the distance between the points. This value is returned as the radius of the circle. • parameters: x1, y1, x2, y2 • return: value representing the radius • calculateArea: Receives the radius of a circle, calculates and returns the area of the circle. • parameters: radius • return: value representing the area • calculatePerimeter: Receives the radius of a circle, calculates and returns the perimeter of the circle. • parameters: radius • return: value representing the perimeter. The output should clearly display the radius, area, and perimeter of the resulting circle. INPUT VALIDATION: Make sure values for x and y in both the center and point on the circle contain numbers.

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.
The formula for calculating the area of a circle is:
A = Tr2
The formula for calculating the perimeter of a circle is:
C = 2Tr
Your program must have at least the following functions:
• calculateRadius: Receives the x-y coordinates of the center and point on the circle (as input by the user) and calculates the distance between the points. This value is returned as the radius
of the circle.
• parameters: x1, y1, x2, y2
• return: value representing the radius
• calculateArea: Receives the radius of a circle, calculates and returns the area of the circle.
• parameters: radius
• return: value representing the area
calculatePerimeter: Receives the radius of a circle, calculates and returns the perimeter of the circle.
• parameters: radius
• return: value representing the perimeter.
The output should clearly display the radius, area, and perimeter of the resulting circle.
INPUT VALIDATION: Make sure values for x and y in both the center and point on the circle contain numbers.
