The radius of a balloon joigmjle:(+ (k:yn0u izs- dg7to .y-is measured to bdm p; fp8tlaaey5 sqn u66/w;b.gb6x3e $20.0 \pm 1.0 \; cm$. 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 cak/ x*0ai1t skx5sglc /lculated by raising a linear dimension to the power of three. Hence thkk50xs t*sgx 1cil// ae percentage uncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
