Question 232659
A large, irrigated crop circle is 400 meters in radius. Correct to the nearest tenth of a hectare, how many hectares of land are contained in this circle.
A = {{{pi*r^2}}}
A = {{{pi*400^2}}}
A = 502654.8246 sq/meters
:
We know a hectare is 10,000 sq/meters
{{{ 502654.8246/10000}}} = 50.3 hectares
