Hmm - you're only getting four digits of result. Normally we'd say that's not very accurate.

For this kind of calculation the calculator does need to do more work than usual - it helps to have an internal value for pi which is twice the number of digits displayed - but from a user perspective, how it does it isn't the same question as how accurate it is. Because the input value is close to pi, there's a possibility of loss of precision, which is what we see here.

To be fair to TI, most calculators don't do much better and may even do worse.
