This is similar to the following question: https://web2.0calc.com/questions/if-three-straws-are-chosen-at-random-from-a-set-of-9-straws

 

The total number of ways to pick the 3 straws = $8 \choose {3}$  $ = 56,$ so the total is 56. See if you can find the favorable on your own :)

In a circle, "the center-radius form of the circle equation is in the format $(x – h)^2 + (y – k)^2 = r^2,$ with the center being at the point (h, k) and the radius being r." So, $(x - 5)^2 + (y + 2)^2 = 16$ is an equation of a circle centered at $(5,2).$ However, our rectangle has a vertex at the center! Thus, the area of the intersection will be $\frac{1}{4} \cdot 16 \cdot \pi,$ or $4\pi.$
