Answer:

Explanation:

Let's get the equation first and then look at the circle when it has been graphed.

(x - 2)^2 + (y - 4)^2 = 7^2

(x - 2)^2 + (y - 4)^2 = 49

  • You will notice that the center of the circle has been marked and it is at (2,4) just as the question required.
  • Another point has been added. It is at (2,11).
  • It is the radius of the circle
  • 11 - 4 = 7 which is the radius that has been requested
