You are trying to install a pool. you need to do some calculations. You will write a Java program named "Circle", that will calculate the area, circumference and volume of the circle. You will need to define some variables. The variables you need include, radius, area, circumference and volume as well as a final variable for pi (be sure to do the initializations). you should use a final pi with your initialization. Your user will be prompted to supply a radius. diameter = 2* radius Volume is calculated by Volume=4/3*m*radius The circumference of a circle can be found by multiplying pi (T = 3.14) by the diameter of the circle. Remember, diameter is 2* radius. Square the radius and multiply by pi to find the area of the circle. When finished, the answers should appear for the end user This project should repeat any number of times for our user. You will have to identify the sentinal token to the user. (Use an outer while loop that identifies new circles.
