The radius of a balloon is measured9yltx ,sh0i,b to be+qa r. n62etwg $20.0 \pm 1.0 \; cm$. 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 rad:j-c,md*jv-c9c wlndius is 5%. Volume is calculated by raising a linear dimension to thed :ldj-,jcnwv- mcc*9 power of three. Hence the percentage uncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
