Question

The center of circle Q has coordinates (-5, -2). If circle Q passes through T(-5, 8), what is the length of its diameter?

Answer 1

It's diameter would be 12

Explanation:

To find the radius of the circle, you have to find the distance between two points, the difference between (-5,-2) and (-5,-8) is 6. Since diameter is twice the radius, the diameter would 12.
