THE TOPIC IS: AREA OF CIRCLES WHATS THE ANSWER?? I WILL GIVE YOU BRAINLIEST AND A THANKS <33

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

if you was gonna solve for a, a is a   < -12

the answer is a beach is the best place to be

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
