2a+10b-c + -3a +5b + c = -a +15b
So,
The diameter is 8.6ft. We need to convert to radius.
2 radius = 1 diameter
8.6/2 = 4.3 ft.
3.14(18.49)
58.0586ft.²
Divide by 2 (semi-circle)
29.0293ft.²
0 0 (0,0)
11 2 (11,2)
22 4 (22,4)
33 6 (33,6)
-3x+y=10 is the answer. If you plug the coordinates in to the respective spots (-2 for x and 4 for y), you will get an equal true statement.
