Question

the equation of circle c is (x-5)^2+(y-2)^2=64 find the center and radius of circle C

Answer 1

Answer:

Center:  (5, 2); radius:  8

Step-by-step explanation:

Compare the given equation to the standard equation of a circle with center at (h, k) and radius r:

(x-5)^2+(y-2)^2=64

(x - h)^2 + (y - k)^2 = r^2

Then r must be √64, or 8.  h and k are 5 and 2 respectively.
