Answer:
2. 9pi
3. 72 + 9pi
Explanation:
2. There are two semicircles with a diameter of 6, meaning that the total area of the two semicircles is the area of a circle with diameter 6, which is 9pi (pi * r^2) where r = 6/2 = 3
3. Just add the first and second answers together to get 72 + 9pi. If the question wants a decimal answer just replace pi with 3.14159
