Question

Find the center and radius, then write the equation of each circle.

Answer 1

So the equation of the circle is (x-h)²+(y-k)²=r² with the center being at point (h,k) and radius being r.
So for the first one:
Point is (5,4), the radius is 3.
Therefore, the equation should be (x-5)²+(y-4)²=9

For the second one,
Center is (4,3), the radius is 5.
Therefore, the equation should be (x-4)²+(y-3)²=25
