Problem
ignment 11-1 \&1-2 Sketch the graph of the following circle. \[ x^{2}+(y-3)^{2}=25 \] (a) Find the center of the circle. (b) Find the radius of the circle. (c) Graph the circle. (a) Find the center of the circle. (Type an ordered pair.)
Solution
Step 1 ：Center: \((h, k) = (0, 3)\)
Step 2 ：Radius: \(r = \sqrt{25} = 5\)
Step 3 ：Circle: (x-0)^{2} + (y-3)^{2} = 5^{2}
