RE: Can someone do a calculation on a TI Inspire CAS?
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.
