He figure is rotated counterclockwise. Which rotation could have taken place? a 45° rotation
a 90° rotation
a 135° rotation
a 225° rotation

a 90° rotation

I'm not sure about answer...

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
