Test and analysis: calculate the diameter according to the volume formula of the ball, and then the constant in the option is A: B, which means π. Substitute the four options one by one and find the one closest to the true value. Set the constant in the option to? We can see that option A is substituted, option B is substituted for π= =3, option C is substituted, and option D is substituted, so the value of d is close to the real value, so D is chosen.

Comments: This question mainly examines the volume formula of the ball and its estimation, and at the same time examines the calculation ability, which belongs to the intermediate question.
