During a recent blizzard Jack made two snowballs, one of which had twice as large a diameter than the other. As usual the weather warmed up and the snowballs began to melt. The melting only took place at the surface of the snowballs, so the speed at which they melted was proportional to the remaining surface.

How much was left of the small snowball when half of the volume of the large snowball had melted?

A) Approximately 20.27%

B) Approximately 30.42%

C) Approximately 50%

D) Approximately 10.75%
