Any answer less than one would work, soothe answers are A and D
Answer: its b
Step-by-step explanation:
bc i used a calculator and it said so
1: (pi)5^2 = 78.54 then multiply that by 11 and you get 863.94
2: (pi)13^2= 530.93 then multiply that by 8 and you get 47247.44
3. (pi)18^2= 1017.88 then multiply that by 22 and you get 22393.36
I think it is a)57 because 84-27=57 or b because it is less than 90
