Rate = total questions / total time

Malcolm = 15 / 18 = 0.833 problems per minute

Diedra = 16/ 17 = 0.941 problems per minute

The area of the circle is 16*16*pi=256pi.  We can calculate 3/4 of the circle's area for the part not represented by the triangle and the shaded area, and then add in the triangle.  3/4 of the circle's area is 192pi.

The triangle is a right triangle with two legs of length 16.  Therefore, it's area is 16*16/2=128, and the total area is 192pi+128, or 731.2.
