I’m missing whether the 40 yd label is the radius or the diameter. Here are both possibilities:
If 40 yd is the radius (r = 40 yd)
- Circumference = 2πr = 80π yd ≈ 80π ≈ 251.3 yd
- Area = πr^2 = 1600π yd^2 ≈ 1600π ≈ 5026.5 yd^2
If 40 yd is the diameter (d = 40 yd → r = 20 yd)
- Circumference = πd = 40π yd ≈ 40π ≈ 125.7 yd
- Area = πr^2 = 400π yd^2 ≈ 400π ≈ 1256.6 yd^2
Tell me which label is intended and I’ll confirm the correct one.
