3. One of the objects used in this lab is a heavy ring (see figure to F R, = 0.254 m the right). If this ring will be approximated as a hoop, what error is R = 0.225 m introduced by this approximation? Hint: Calculate the moment of inertia by using the equation for an M = 4.195 kg annular cylinder (true value) and then repeat it by using the equation for a hoop (approximate value), then use the percentage error formula to calculate the error due to this approximation
