Back

The equation is already in standard form, where the center is (0, 0) and the radius is 5.

What is the relationship between the diameter and radius of a circle?

Back

Front

How do you determine if a point lies inside, on, or outside a circle?

Back

To determine this, calculate the distance from the point to the center of the circle. If the distance is less than the radius, the point is inside; if equal, on the circle; if greater, outside.
