Java program to enter the radius of a circle and find its diameter circumference and area. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle or any two points on the circle as long as they are exactly 180 degrees apart. So if we think about the entire circle what is the area going to be.

And they want us to figure out the area of the surface of this candy or essentially the area of this circle. Enter the area contained within a circle. Max is building a house.

We know that the area of a circle is equal to pi times our radius squared. It can also be defined as the longest chord of the circle. The formula used to calculate the circle diameter is.
