A: cost= 3*55+.35m
B: cost=3*50+.40m
set the costs equal, and solve for m.
The first number is 27 and the second number is 45 so the ratio would be 27;45
(0,-4) would map into itself because it doesn’t move.
R^2/2(pi/180*D-sin(D)) is the formula so 6^2/2(pi/180*120-sin(120)) is the problem which comes to about 22cm^2
