Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
Diameter, d = Circumference/piRadius, r = d/2 Area = pi*r2.
Area = Pi(d/2)2 where d = diameter
Area = pi*r2 where r = d/2 So area = 314.16 sq metres approx.
Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.
