Answer:
555.94
Step-by-step explanation:
16 x 11 = 176/2
88
since there are two of the same triangle
88 x 2
176
11 is the radius
A = 

A = 3.14 ( pie is 3.14, if not then pi) x (11x11)
A = 3.14 x 121 (or 121
)
A = 379.94
379.94 + 176 (or 121pi + 176)
555.94
3. Acute
4. Right
5. Acute
Hope this helps!
Well if you make it to slope intercept it would be y=-1/2x-2 so you start at -2y at 0x and it goes down one for every time it goes over two
