How does one even solve this?

I have a teacher who really enjoys NOT teaching the class math. Can someone help me solve this, because I don't even know where to start?

The question for this is:
Find the area inside the semicircle and outside the triangle in terms of pi.

What are the width and height of a right triangle whose legs you know? Ok now you have the area of the triangle. How about the semicircle? What is its diameter? Do you know a formula that would give you the diameter from the information you're given? Now that you have the diameter you can compute the area of the circle with that diameter; and the semicircle has half that area. Finally, the gray shaded areas are the area of the semicircle minus the area of the triangle. Thanks from topsquark, romsek and Luna1201
