This is a pie chart maker. The values to be entered and values to be calculated for are as given in the table. The relative weights of the pie slices can be any set of numbers where each number represent the amount or quantity of each slice relative to the other slices. These relative weights will be recalculated into percent of the whole pie. The angle of the slice is calculated also to be used when drawing the pie chart with the aid of a protractor. The chord of the arc of slice is also calculated to provide an alternative method to drawing the slices with a protractor. Choose a point on the circle as the starting point of the calculated chord and find the other point on the circle where this straight length intersects with the circle. Draw lines from the center of the circle to these two point to create the slice. The total percent is also calculated as a check and it should be 100. The total of the angles is also calculated as a check and it should be 360. The radius of the circle is needed to be able to calculate for the chord lengths of the slices. The angles of the slices are not affected by the radius length.
