A large, irrigated crop circle is 600 meters in radius. Correct to the nearest tenth of a hectare, how many hectares of land are contained in this circle.
To find the number of hectares in a large, irrigated crop circle, we first need to calculate the area of the circle in square meters and then convert it to hectares.
The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius of the circle.
Let's calculate the area of the circle:
A = πr^2
= 3.14 * (600m)^2
= 3.14 * 360,000m^2
= 1,131,600m^2
Now, we need to convert the area from square meters to hectares. There are 10,000 square meters in 1 hectare.
Area in hectares = Area in square meters / 10,000
Area in hectares = 1,131,600m^2 / 10,000
= 113.16 hectares
Therefore, the large, irrigated crop circle contains approximately 113.2 hectares of land.
