The point (0,5) lies on a circle that is centered at the
origin. Does (-3,-4) also lie on the circle?
1. Identify the radius from the graph.
r= units
2. Determine the distance from the center to
(-3,-4) using the distance formula.
distance = units
3. Compare the radius to the distance. Does the
point (-3,-4) also lie on the circle?

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
