The circumferences of two circles are 264 meters and 352 meters. Find the difference between the areas of the larger and the smaller circles?  Choose one
A) 4372 sq m	B) 4317 sq m	C) 4312 sq m	D) 4372 sq m	E) 4712 sq m
Let the radii of the smaller and the larger circles be s m and l m respectively.   2∏s = 264 and 2∏l = 352   s = 264/2∏ and l = 352/2∏   Difference between the areas = ∏l2 - ∏s2   = ∏{1762/∏2 - 1322/∏2}   = 1762/∏ - 1322/∏   = (176 - 132)(176 + 132)/∏   = (44)(308)/(22/7) = (2)(308)(7) = 4312 sq m   Answer:4312 sq m
