(a) Interpretation: The area in square meters of a circular skating rink that has a 12 .5-m radius is to be calculated. Concept introduction: The metric system unit is the unit system which is accepted as the standard system of unit internationally. Thenonmetric units are the common unit system which is not standard for the parameter to be calculated.
