The area of a square cake is going to be:\[9*9\]

OpenStudy (kendricklamar2014):

The area of a round cake is going to be: \[\pi*4^2\]

OpenStudy (kendricklamar2014):

Now, what is 9*9 @js7474

OpenStudy (anonymous):

81

OpenStudy (kendricklamar2014):

Yes, now\[4^2 = 16\]

OpenStudy (kendricklamar2014):

So what is \[3.14 * 16\]

OpenStudy (anonymous):

50.24

OpenStudy (kendricklamar2014):

Yes now 81-50.24 = about 30
