The circumferences of two circles are 396 meters and 704 meters. Find the difference between the areas of the larger and the smaller circles?
Choose the correct answer
A) 29960 sq m
B) 26950 sq m
C) 43120 sq m
D) 27680 sq m
E) 27786 sq m

Rationale: "let the radii of the smaller and the larger circles be s m and l m respectively . 2 ∏ s = 396 and 2 ∏ l = 704 s = 396 / 2 ∏ and l = 704 / 2 ∏ difference between the areas = ∏ l ^ 2 - ∏ s ^ 2 = ∏ { 198 ^ 2 / ∏ ^ 2 - 352 ^ 2 / ∏ ^ 2 } = 198 ^ 2 / ∏ - 352 ^ 2 / ∏ = ( 198 - 352 ) ( 198 + 352 ) / ∏ = ( 154 ) ( 550 ) / ( 22 / 7 ) = 26950 sq m answer : b"
Answer: B
