The Area Calculator included in the Web Machinist program (bottom) calculates the
area of circles, squares, rectangles and hexagons (above). In this example of a
hexagon area calculation the Area Calculator not only calculates the area of the
hexagon but also calculates the distance across the points and the width of the flats.

The Rectangle and Square Calculators not only calculate the area but also calculates
the distance across the points and the perimeter distance.

Above is an example of a square area calculation.

The circle area calculator calculates the area of the circle, radius of the circle
and the circumference of the circle.
