How much additional string, to the nearest 100th of an inch is needed?

It's just 2 * pi, or 6.28 inches because it's the difference of the diameter by 2 inches.

Are we assuming that 25,000 miles of string is not going to stretch?

I think the better question is how much longer is the mean orbital distance of the moon in the summer vs the winter?

I'll take my answer off the air.

46,000 miles ( Globe circumfrence 22000 X .00021 x 3.14etc plus a few feet lost to carless cutting) 3,212,640,000 inches exactly. Though it shrinks when it gets wet so watch out for the oceans

I will tell you if you tell me how many drops of water are in the ocean to the nearest drop.

6.28" it's a trick question to get you to do lots of unnecessary calculations.

If you dont know the answer your an idiot and belong with your idol G.Bush you coward.

Do your own math. C = pi * D.
