Fixed Area Plot, Acres

Spike VM

Determine the area in acres, for a circular plot

Formula used:
A = πR² ÷ 43560 (there are  43560 ft² in one acre)
where A = area
R = radius
π = 3.14159
example:
diameter of plot = 66 feet (ft)--R = diameter ÷ 2
66  ÷  2  =  33  ft for the radius
3.14159 * ( 33*33) ÷ 10000 = A
3.14159 * 1089 =  3421.19151 ÷ 43560 = 0.07853975 acres (ac) or 1 ÷ 0.07853975 = 1 :  12.7 of an  acre (ac)
