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. Last edited by skipjack; March 5th, 2019 at 10:51 PM.

Hints: What is the area of any triangle in general? It's half the width times the height. 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.
