Ever wonder why an 8" hole is so much more work than a 6"?
Here's the formula for a cylinder's volume. V=pi(r^2)xH Volume = pi x radius squared x height
We'll assume a foot of ice for these calculations:
8" V=3.14(8^2)x12 = 2411.52
6" V=3.14(6^2)x12 = 1356.48
An 8 inch hole is 1.77 times more ice removed than a 6"! Thats almost twice as much more ice! Just a little food for thought...
So the next time you and your friend go fishing and he drills 100 holes with his 6" and you drill 100 with your 8", tell him you smoked him because you drilled 177! (If your arms don't fall off first...)
