The diameter of a circle is 8 meters. What is the circle's circumference?

C =  8pi meters or approximately 25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d  where d is the diameter

C = pi *8 meters

If we approximate pi as 3.14

C = 3.14 *8

C=25.12 m

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

square root
