Answer:
C) 314 feet.
Explanation:
We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.
The distance around the track would be equal to circumference of circle.
, where r represents radius of circle.
Since we have been given across distance, so it will be diameter of track.
To find radius we will divide across distance by 2.

Upon substituting our given values in circumference formula, we will get:



Therefore, the distance around the track is 314 feet and option C is the correct choice.
