Answer:
314.16 m
Step-by-step explanation:
The distance across the track is 100 metres. This means that the diameter is 100 m.
The track is circular, so, we need the circumference.
The circumference of a circle is given as:
C = πD
where D = diameter
Therefore, the circumference of the track is:
C = π * 100 = 314.16 m
She walked a distance of 314.16 m
