Re: divide by pi??

The easiest thing to do here would be to use a calculator.

If you took pi as being 3.14, then you could technically do it by long division, but a calculator is much simpler. If you take pi as being 3.14, then you get 57.9618 when rounding up to 4 decimal places, and if you take pi as pi (or at least, the much more accurate version of pi as found on my calculator), then you get 57.9324.


Why did the vector cross the road?
It wanted to be normal.

Re: divide by pi??

Do you know how to do decimal division?  This is no different.
