The circumferences of two circles are 132 meters and 352 meters. Find the difference between the areas of the larger and the smaller circles?	Select
A) 2996 sq m B) 2897 sq m C) 4312 sq m D) 5768 sq m E) 8470 sq m
Let the radii of the smaller and the larger circles be s m and l m respectively.   2∏s = 132 and 2∏l = 352   s = 132/2∏ and l = 352/2∏   Difference between the areas = ∏l^2 - ∏s^2   = ∏{66^2/∏^2 - 132^2/∏^2}   = 66^2/∏ - 132^2/∏   = (66 - 132)(66 + 132)/∏   = (110)(242)/(22/7)   = 8470 sq m   Answer:8470 sq m
