The radius of a balloox/4av j1rft/q h 2eq) 9f8qlqxn is measured 4m+k9y tkwhiv;l:z e e3/rw.jw*fxu5 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 tho)x0-by + wfdfe radius is 5%. Volume is calculated by raising a linear dimension to the power of three. Hence the percentage uncertainty in the volume will be three times that of t0 )wf od+b-fyxhe percent uncertainty of the radius which is 15%
