Answer 6

we need a method of attack on it, i assume you already know what the graph of it looks like

Answer 7

no. let me find out

Answer 8

the functions themselves give us our radius measures

Answer 9

ok

Answer 10

To find the area of a circle we take the largest radius: R and use it in the formula for the area of a circle: pi R^2

we then subtract, or take away the area of the inner circle that is created by the radius function for "r": pi r^2

Answer 11

does that make sense?

Answer 12

Yes. Thank you. I'm going to try this on my own. Once i get my answer, I'll send it to you. From there on, you can tell me what i didn't do, or did incorrectly. Thanks for the help so far.
