Perimeter = 123.36 m P of full circle = 123.36 m x 2 = 246.72
P of circle (circumference) = Pi x diameter 246.72 = 3.14 x diameter 246.72/3.14 = diameter Diameter = 78.57 Diameter= radius x 2 78.57/2= radius Radius = 39.28
Area of a full circle = Pi x r^2 A=3.14x39.28^2 A=1543.44 mètres squared
Area is semicircle = 1543.44/2 A=771.72 mètres squared
