The radius of a circle is a measure of a straight line segment extending from the center of the circle to its outer edge. Because a quarter circle represents one fourth of a circle, the area of a quarter circle is one fourth the area of the circle. The radius of a quarter circle is...

The example below is similar to one above although, since we have a semi-circle we need to calculate a fraction (one-half) of the circle’s area. Note in this example the diameter, and not the radius is shown. Example: Decisions! Combine? Subtract It is common to have more than one...
