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 = 3.14159example:
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)
