[填空题]
The radius of a balloon i m8oy(l(pr* p*onfr;)okaqd8 s measus ;o:ixj 65h2ds:mircred to be $20.0 \pm 1.0 \; cm$. What is the percentage uncertainty in the calculated volume of the balloon?   % (please exclude the $\%$ symbol with your answer and treat the balloon as a sphere)

参考答案: 15.0


本题详细解析:
The uncertainty in the radius is 5%. Volume is calculatec fgl-8-p g;v6cwzui (d by raising a linear dimension to the power of three. Hence the percentage uncertainty in the volume will be three times that of the percent uncertainty of the rad6-p- l gc(ui8cwzg f;vius which is 15%
