Fixed Area Plots, Hectares

Spike VM

Determine the area, in hectares, for a circular fixed area plot.

Formula used:
diameter ÷ 2 = radius
A = πR² ÷ 10000 (there are 10000 m² in one hectare)
where A = area
R = radius
π = 3.14159
example:
diameter = 15.96 metres (m)
15.96  ÷  2 =  7.98 -- radius = 7.98 metres (m)
3.14159 * ( 7.98 * 7.98) ÷ 10000 = A
3.14159 * 63.6804 =  200.057707836  ÷ 10000 = 0.02 hectare  or 1 ÷ 0.02 = 1 : 50 of a hectare
