参考答案: 15.0
本题详细解析: The uncertainty in the radius is 5%. Volume is calculated bb(ajvivsy / .2 tb+es;rp 6e*ny raising a linear dimension to the power of i6b2+n*ae;yjveb(t vspr/. s three. Hence the percentage uncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
