What is the Af constant value, defined as the area of a field?

Explanation:
Af represents the area of the field. For a circular field, area is A = πr^2. If the field has a radius of 0.05 m, then A = π × (0.05)^2 = π × 0.0025 ≈ 0.00785398 m^2, which rounds to 0.00785. That matches the given value exactly. The other numbers don’t correspond to that area for a 5 cm radius circle, so they’re not correct.
