Estimated volume of a golfball?

[motionman04]

Whats the estimated size your average golfball? Not the exact, but just an estimate? I tried 10 and 100 cm cubed but both were wrong.

The diameter of a golf ball is about 4 cm.

Hmm...I'd estimate a golf ball to be a bit smaller than that. Maybe 2 cm diameter, so 1 cm in radius? Any golfers around to lend a hand with a ruler?

motionman, what formula is used to calculate the volume of a sphere? Even for an estimate, you need to know the formula to get close.

Here's the standard:
The diameter of the ball shall not be less than 1.680 inches (42.67mm). This specification will be satisfied if, under its own weight, a ball falls through a 1.680 inches diameter ring gauge in fewer than 25 out of 100 randomly selected positions, the test being carried out at a temperature of 23 +1°C.
