I am pretty sure that to find the area of a circle, it’s pi times radius squared.
So in your situation, the formula would be p89 squared. So first, multiply 89 times 89, which equals 7921. You could leave it and say the answer is 7921 pi squared, or you could multiply 7921 by 3.14 (pi rounded), which would get you 24871.94 So the answer would either be:
1.) 7921 pi squared
2.) 24,871.94 feet squared

The answer is B. Hope this helps!(:
Answer:
r=5
Step-by-step explanation:
1.simplify both sides of the equation.
2.substract 2r from both sides.
3.substract 12 from both sides.
4.multiply both sides by 5/(11)
5. your answer will be 5.
r=5
