The radius of the circle is half of the diameter, so it is 8 meters.
The formula for the area of a circle is: A = πr², where π (pi) is a constant approximately equal to 3.14 and r is the radius.
Substituting the values we have:
A = π(8m)²
A = 64π
Approximating π to 3.14:
A ≈ 64 × 3.14
A ≈ 201.06
Therefore, the area of the circle is approximately 201.06 square meters.
