The radius of a balloog/pi sk3t.q t.lr1g:y n is measured to be f/cjanb / s5pk 0,lkfq z1l*q7$20.0 \pm 1.0 \; cm$. 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 raising a linear,qv;4cao+o r2: wg lp nu-,k fw4u)yub dimension to the power of three. Hence the percentage u4wokfwy-;bu+gnr , la,p:c42ou q )vuncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
