(a) Explanation Diameter of cylinder is given as 12.559 cm. It has 5 significant digits. Height is given as 5.62 cm. It has 3 significant digits. Outside total area depends on both diameter and height. Note that among the depending physical quantities, height has less number of significant digits, which is 3. So, the final result will be also correct up to 3 significant digits only. Conclusion: Total outside is correct up to 3 significant digits only. Thus, option (2) is correct. Suppose either height or diameter has only 2 significant digits, result also would be correct up to 2 significant digits only... (b) To determine Total outside surface area in cm 2 .
