<PRE><B>Question 997071</B>
.
A bicycle chain fits tightly around two gears. What is the distance between the
centers of the gears if the radii of the bigger and smaller gears are 9.3 inches
and 2.4 inches, respectively, and the portion of the chain tangent to the two
gears is 26.5 inches long? 
----------------------------------------------------------------------


d = {{{sqrt((9.3-2.4)^2 + 26.5^2)}}} = {{{sqrt(6.9^2 + 26.5^2)}}} = 27.38 in (approximately).
