[填空题]
The radius of a balloon),rgur -d r4e25 lo;if cwve)n be );e) pthkk4is measured to be $20.0 \pm 1.0 \; cm$. What is the percentage uncertainty in the calculated volume of the balloon?   % (Remember to keep three significant figures and 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%. mfk 2+fsko q+n:p3/s 3 o3otelVolume 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 the percent uncertainty of the radius w3l:+p+ ks3qoo3/o ekt2f mnf shich is 15%
