a figure consists of a square and a semicircle ,as shown in the diagram below. if the length of the square is 6 , what is the area of the shaded region ?
the area of a circle is a= 2 pi r ... so just Take half of that pi (radius) ... and the radius is 3 because 6 is the length across the circle ot the diameter and the diameter is 2 times the radius... your answer is 3.14 (3) = 9.42
