The circumferences of two circles are 264 meters and 352 meters. Find the difference between the areas of the larger and the smaller circles. Answers.
A) 3566	B) 5467	C) 4132	D) 3526	E) 3782
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: Option 4132
