**Reiny**, Friday, April 27, 2012 at 11:59pmwrite the circle equation in standard form by completing the square

x^2 - 14x + 48 + y^2 - 150y + 5625 = -49 + 49 + 5625

(x-7)^2 + (y - 75)^2 = 75^2

so the centre is at (7, 75) and the radius is 75

after making a sketch you should be able to answer the question
