1. True or False: All points on a circle are the same distance from the center.

2. If center = (0,0) and radius = 5, is point (3,4) on the circle?

3. Identify the center and radius: Circle equation (x−2)² + (y+3)² = 16

4. True or False: A circle can have different radii at different points.

5. Give a real-life example of circles.

Answer Key
