Use the interactive Geogebra applet lower on this page to solve the following problem:The graph of a semicircle with a radius of 2 units is shown in the diagram. A chord parallel to the x-axis divides the semicircle into two regions. The upper shaded region is a segment of the semicircle. The distance that the chord is from the x-axis is h. Find the distance h such that the area of the segment is one-half the area of...
