Find the circumference of each circle.
7) diameter = 22 km

Step-by-step explanation:

Diameter (d) = 22 km

circumference(c)

= π d

= 3.14 * 22

= 69.02 km

Hope it will help :)

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
