There is a circle of radius 1 cm. Each member of a sequence of regular polygons S1(n),
n = 4, 5, 6, …, where n is the number of sides of the polygon, is circumscribing the circle: and each
member of the sequence of regular polygons S2(n), n = 4, 5, 6, … where n is the number of sides of
the polygon, is inscribed in the circle. Let L1(n) and L2(n) denote the perimeters of the corresponding
polygons of S1(n) and S2(n), then {L1(13) + 2pie}/ L2(17)
is
a. greater than pie/4 and less than 1
b. greater than 1 and less than 2
c. greater than 2
d. less than pie/4
