28) B. --- radius is 3.3, so 3.3^2 = 10.89
29) C. --- The shaded area is a trapezoid. The area of a trapezoid is (b1+b2)/2 * h. Plugging values in, you get (9+8)/2 * 8 = 68. (8 is the height based on the diameter of the circle) So you then take 68 and subtract it by the radius^2*pi, resulting it answer C.
30) D. none of the above -- I got a completely different answer than the ones provided.
