Question
Calculate the perimeter of a circular field with an area
of 3675 square meters, using an approximation of Ο as 3.Solution
Let the radius of the circular field = r m So the area of the circular field = Ο Γ r2 = 3675 r2 = 1225, r = 35 So the circumference of the circular field = 2 Γ 3 Γ 35 = 210 m
