$L = 2 C + 1.57 ( D + d ) + \frac { ( D - d ) ^ { 2 } } { 4 C }$

$L = 2 C + 1.57 ( D + d ) + \frac { ( D - d ) ^ { 2 } } { 4 C }$ will determine the length of a cross belt that goes around two pulleys, where $C$ is the distance between the centers of the pulleys, $D$ is the diameter of one pulley, and $d$ is the diameter of the second pulley. Find the length of the belt if the distance between the centers of the pulleys is 28 in., the diameter of one pulley is 18 in., and the diameter of the other pulley is 8 in. Round to the nearest inch.

A) 98 in.
B) 101 in.
C) 97 in.
D) 103 in.
