[填空题]
The radius of a ball2c7osqw/(r+ygw :lef 1yb652 n l j0arao:kmpfx))kzd7 s+txoon is measured 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 the radius is 5%. Volume is calculated b8m ia7okyk-c r7k*.z fy raising a linear dimension to the power of three. Hence the percentage uncertainty in the volume will be three times that ok8z aom-y7ri*c7k k .ff the percent uncertainty of the radius which is 15%
