Number of laps 2 4 6 8 10 time 10 20 30 40 50 charlie runs laps around a track the table shows how long it takes him to run different number of laps how long would it take charlie to run five laps

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

first one is a: renaming a fraction. second one is c: de-c
