参考答案: 15.0
本题详细解析: The uncertainty in the radius is 5%. Volume is calculated by ra vrro1uafldmf5 o -:u7mp 2,y0ising a linear dimensidrv7ym oalr2 f,o0f:1uum- p5 on to the power of three. Hence the percentage uncertainty in the volume will be three times that of the percent uncertainty of the radius which is 15%
