I honestly don’t know but I really need this so I can get my answer as well , good luck though .
I am not answering all the questions.
I will only do the first one.
A = pir^2
A = pi(6)^2
A = 36pi
You do the rest.
Replace x with -1, and y = 9
Therefore, (x²y)/-7 becomes (-1² · 9)/-7
-1² is just 1, and 1 × 9 is just equal to 9, so your final answer is -9/7.
