Question
What is the difference between (in m2) the
area of a circular field of radius 14 metres and area of a rectangular piece of land having its dimensions as 15 metres Γ 25 metres?Solution
Area of the circular field = Ο Γ radius2 = (22/7) Γ 14 Γ 14 = 616 m2 Area of the rectangular piece of land = length Γ breadth = 15 Γ 25 = 375 m2 So, difference in area = 616 β 375 = 241 m2
