Tell me how u got scared one day

My dog jumped on my face when I was sleeping

Step-by-step explanation:

We all have fears from time to time. That's true no matter how big we are or brave we can be. Fear can even be good for you sometimes and even help you stay healthy. Fear of getting too close to a campfire may save you from a bad burn. And fear of getting a bad grade on a test might make you study more.

Being a bit on edge also can sharpen your senses and help you perform better in a recital or during a track meet. Some people even enjoy being a little scared. That's why they like to watch scary movies or go on roller-coaster rides.

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
