What is the area of the shape below? Each of the measures is in inches. 
The top and bottom rectangles have an area of 7 in × 2 in = 14 in2. The center rectangle has an area of 11 in × 6 in = 66 in2.
Adding the area of each of these rectangles up, we get a total area of: 14 + 66 + 14 = 94 in2.

A circle of radius 
is inscribed in a semicircle, as shown. The area inside the semicircle but outside the circle is shaded. What fraction of the semicircle's area is shaded? (Hint: the radius of semicircle is 4.)
Area of the circle inscribed inside the semicircle 
Area of the larger circle (semicircle's area x 2)
(4, or the diameter of the inscribed circle is the same thing as the radius of the semicircle). Thus, the area of the semicircle is 
Part of the semicircle that is unshaded is 
Therefore, the shaded part is 
Thus the answer is
