Given the standard equation of a circle, (x - 2)² + (y + 4)² = 25, match the center and radius to the proper coordinates and value respectively.

Arrange the following steps in finding the center and radius of a circle given an equation in general form.

Fill in the blank: __________ is the set of all points in a plane that is located a fixed distance from a fixed point.

Fill in the blank: The distance across a circle passing through the center is called __________.

What is the center of the circle whose equation is (x-2)² + (y+5)² = 13? Note: Answer in this format (x,y) and do not include space.

What is the radius of the circle whose equation is x² + (y-4)² = 144? Note: Your answer must be a number only, no letters or symbols.

Match the correct standard form of the equation to the correct graph of a circle.
