On a grid mark A(-1,0) and B(7.28,0). Find C which is the midpoint of A and B (3.14,0) and draw the semicircle with origin at C that runs from A to B above the x axis (r = 4.14). Draw a line segment from O along the positive y axis to the semicircle at D. |OD| = √|OB| = √7.28 Measure OD with compasses and mark the length from O towards B.
