Will have to compare volume amount of the pans
rectangular pan we do lxwxh
13x9x2=234in^3 cake batter
cylinder pan we do [tex] h\pi r^{2} [/tex]
[tex]2 \pi 4^{2} [/tex] = 100.531
and since we get two round pans, the total amount of batter we get from round pans are around 201.062
so rectangular pan wins with more cake batter.
