The circumferences of two circles are 660 meters and 704 meters. Find the difference between the areas of the larger and the smaller circles?
Pick
A) 2996 sq m
B) 4774 sq m
C) 4312 sq m
D) 2768 sq m
E) 2786 sq m
Let the radii of the smaller and the larger circles be s m and l m respectively.   2∏s = 660 and 2∏l = 704   s = 660/2∏ and l = 704/2∏   Difference between the areas = ∏l^2 - ∏s^2   = ∏{330^2/∏^2 - 352^2/∏^2}   = 330^2/∏ - 352^2/∏   = (330 - 352)(330 + 352)/∏   = (22)(682)/(22/7)   =4774 sq m   Answer:4774 sq m
