Well, SAT Q’s way is somewhat more tortuous, but still viable.

( n / 360 ) * ( 2 * pi * r ) = 6
( n / 360 ) * ( 2 * pi * ( r + 3 ) ) =
( n / 360 ) * ( 2 * pi * r + 6 * pi ) =
6 + ( n * pi / 60 )

However, since the central angle isn’t given as a variable, no answer choice corresponds to that method. The correct answer is E.
