Answer: The area of the path running around the inside edge of the field is 731.2 m²
If the path is across the middle of the field, the area of that path is about 245m²
Explanation:
The radius of the field is 35m, subtracting 3.5 from that leaves the radius of the inside edge of the path at 31.5 m
The area of the path will be the difference between the two areas.
π × 35² = 3848.45
π × 31.5² = 3117.25
3848.45 - 3117.45 = 731.2
If the path is across the middle of the field, use the diameter, 70m, times the width of the path, 3.5m, to find the area of that path: 245m²
I hope this helps.
