[填空题]
The radius of a ballrf.:tyj3sonjjeg mdb)0.. ,4;a nxezoon is m /e6a0b uj7agv;;jrh measured 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 calculated by rai2htao7(g k i(dsing a linear dimension to the power of three. Hiaktdg((72 o hence the percentage uncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
