So, what it is saying in words is 180 is to x as 12 is to 24. So, determine what relates the second half of the problem, which would be 12 is half of 24. Therefore, 12 times 2 is 24. So, x is 360 because 180 times two is 360.
(-1,2) is where it will intersect
The radius is 7 what it is telling you is that you already did the square 4^2*3.14=49 pi.
