try PI * R^2
so 3.14 * 5^2 
then subtract 85 degrees from your answer

anonymous · Answer

Why would I subtract 85 degrees?

anonymous · Answer

well im not sure yet because im debating against myself if you should divide or subtract sorry. :) so maybe try both

anonymous · Answer

3.14 * 5^2 = 78.5
78.5 - 85 = -6.5 
So that would be wrong
85 / 75 = 1.083

Something is missing I think, I'm just not sure what exactly
