So hmm notice the picture below
simply get the area of the segment, and subtract it from the area of the circle, what's left, is the difference
notice your circle, has a radius "r" of 18
Flipping two coins gives four possibilities: HH, HT, TH, TT
So P(TT)=1/4
So we'd expect a quarter of the trials to be two tails.

trials expected to be two tails.
you can subtract from point 1 to point 2
(9,-2) - (8,3)
9-8= 1
-2-3= -5
therefore horizontal leg is 1
vertical leg is -5
you can also sketch and count the units :)
