The radius of a circle can be calculated from the measurements of the length L of a chord and the distance h from the chord to the circumference of the circle from the equation R = L2/2h + h/2. Calculate the radius and its uncertainty from the following values of L and h. (a) L = (125.0 ± 5.0) cm, h = (0.51 ± 0.22) cm (b) L = (125.0 ± 5.0) cm, h = (57.4 ± 1.2) cm Was it necessary to use the second term to calculate R in both (a) and (b)? Explain.
