Step-by-step explanation:

18.85

Step-by-step explanation: You are just trying to find the circumference of the circle, as that would be what the track is. You first must convert the diameter to radius, as that is what the circumference (circumference is just a fancy word for perimeter) equation requires. Diamater is just a line that goes through the circle, while the radius is a line that goes to the middle of the circle, so you just half to divide by 2 to discover the radius is 3.

You then must plug this value into the circumference equation, which is C = 2πr.

C=2π3

C=18.85 is the circumference, rounded to the nearest hundredth.
