Evaluate integral subscript short dash 8 end subscript superscript 0 open parentheses short dash square root of short dash x squared minus 8 x end root close parentheses d x using the following graph. A graph with an x-axis ranging from 11 to 1 and a y-axis ranging from 6 to 6. A uniform curve starts from the point (8, 0) on the x-axis, dips in the third quadrant to the point (4, 4), and then gently rises to reach the origin (0, 0), forming a semicircle with a radius of 4 units
