i use 3.14

Answer 16

right - that accounts for the differtence - what we can say is that 3366 is wrong

Answer 17

To be more accurate you should use the pi on calculator up to 10 decimal places..actually jimmyrep 3,666 is wrong

Answer 18

but then why am i getting 3346?

Answer 19

because you used 3.14 for pi - your calculation is correct

Answer 20

It's because your value of pi is 3.14 you've truncated it to just two decimal places where as the pi on the calculator is more accurate because it's up to 10 decimal places. But yes, your calculation is correct.
