Answer 10

Well, I see that the angle is 40 degrees. I'm trying to think what part of the entire circle that is. How many degrees are in the whole circle?

Answer 11

C = 2*pi*r

C = 2*3.14*9

C = ???

Answer 14

That seems like a big answer. How did you get it?

Answer 15

I did: 360/40= 4
then I did: 2 x 3.14 x 9= 56.52
then I multiplied them both (4 x 56.52) and I got 508.98
