Answer:

Center: 2, -3

Radius: 7

Explanation:

The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.

The radius is equal to the square root of the constant on the other side.

The square root of 49 is 7.
