How many hectare are in a 10 Km circumference?

Answer 1

To find the area enclosed by a circle with a 10 km circumference, we can use the formula for circumference ( C = 2\pi r ). Solving for the radius ( r ), we get ( r = \frac{C}{2\pi} = \frac{10,000 \text{ m}}{2\pi} \approx 1591.55 \text{ m} ). The area ( A ) can then be calculated using the formula ( A = \pi r^2 ), which gives approximately 7.96 hectares (1 hectare = 10,000 m²).
