Answer:
B) 1/4 × 3/6 = 3/24
Step-by-step explanation:
1/4 of the rectangles are colored blue(ish).
3/6 of the rectangles are colored yellow(ish).
The colors overlap in 3/24 of the rectangles.
The problem statement with these numbers in it is that of choice B.
By Green's theorem, the integral of along is
which is 6 times the area of , the region with as its boundary.
We can compute the integral by converting to polar coordinates, or simply recalling the formula for a circular sector from geometry: Given a sector with central angle and radius , the area of the sector is proportional to the circle's overall area according to
so that the value of the integral is
