Answer:
Sara will run 8836 square yards
Step-by-step explanation:
Given that the diameter of the track Sara runs is 75 yards.
The radius is half the diameter, and so, 37.5
Sara will jog 2 laps around the track, therefore, the amount of yards Sara will run is obtained by finding twice the area of the circle she is going to cover.
Area of a circle is:
Where r is the radius
Using r = 37.5
Since she is jogging 2 laps, we have the yards she will cover to be:
2(4417.9)
= 8835.8
Approximately 8836 square yards
