Answer:
The answer is 19
Step-by-step explanation: 13 scored from 91-100, and 6 scored from 81-90, all you have to do is add them together.
I believe it’s pie times radius squared so 6ft = 3.14•3 squares and 8ft = 3.14•4 squares and then subtract
(x-4)^2-19=y
you first add the three to the other side, then add 16 on both sides, make the left side x-4 squared, and lastly you subtract 19 from both sides.
