# Given the equation x^2 + (y-3)^2 = 25 a) What is the Center C?b) What is the length of the radius r?

The standard form of the equation of a circle is: `(x-h)^2+(y-k)^2` , where the center C is (h,k) and the radius is r.

Here, the given equation is `x^2 + (y-3)^2 = 25` . We can rewrite this equation as:

`(x-0)^2+(y-3)^2=(5)^2`

**Therefore, a) the center C is (0,3)**

** b) the length of the radius r is 5 units.**
