It says "eXpress in hundredths" what does that mean?
OpenStudy (sleepyjess):
And I did
42/2
21
21*21*21
9261
9261*4/3
12347.999999999999
12347.999999999999*3.14
38772.72
OpenStudy (sleepyjess):
It means to just round to the hundreds place
TheSmartOne (thesmartone):
Umm
92641x4/3 = 12348
TheSmartOne (thesmartone):
And if you multiply it with the \(\pi\) button you get 38792.3860865
