Question
What is the difference between (in m2) the
area of a circular field of radius 28 metres and area of a rectangular piece of land having its dimensions as 60 metres Γ 40 metres?Solution
Area of the circular field = Ο Γ radius2 = (22/7) Γ 28 Γ 28 = 2464 m2 Area of the rectangular piece of land = length Γ breadth = 60 Γ 40 = 2400 m2 So, difference in area = 2464 β 2400 = 64 m2
