solve the problem-two wheels of radius 15.89cm and 14.29 cm respectively rest on the ground. If the centers of the wheels are 37.85cm apart, how far apart are the points where they touch the ground?
answers can be 34.35cm 37.85 cm 37.82 cm or 35.05 cm

Since the wheels touch the ground directly beneath their centers, they'd be 37.85 cm apart.

no complicated math formulas here just little but of latteral thinking. The points where they touch the ground are exactly the same distance as the centers. The radius is the distance from the perimiter of the wheel to the center. This is simple enough to prove by drawing two circles on graph paper and draw a line underneath the circles. Now draw a dot in the center of each circle and a line from the dots to the line under the circles. The distance between the dots is the same as the distance between the two lines..

37.85.
Although a simple question, the answer can be found by sketching out the problem.
