Round to the nearest hundredth. Very close though.

anonymous · Answer

I used a longer pi than 3.14 and I ended up with 22.45

anonymous · Answer

Yes, you need to be very aware of round off error propagation. Use the pi symbol on your calculator and don't round off intermediate steps....

anonymous · Answer

they told us to use 3.14 no pi

anonymous · Answer

Mkay, then 22.44 is reasonable.

anonymous · Answer

ok

anonymous · Answer

Yes, I agree... if they said to use 3.14, by all means, do so :)
