pizza calculations

Pizza Hut:

12" x 2 -> (3.142*6*6)*2 = 226.2 sq"
9" x 3 -> (3.142*4.5*4.5)*3 = 190.9 sq"

Pay $32 gives you 226.2 sq"
Pay $30 gives you 190.9 sq"

That translates to :
226.2/32 = 7.07 sq" per $1 (2 pizza varieties)
190.9/30 = 6.36 sq" per $1 (3 pizza varieties)

Oishi Pizza:
14" x 1 -> 3.142 *7*7 = 154 sq"

154/$36 = 4.28 sq" per $1


Rocky's Pizza:
16" x 1 -> 3.142*8*8 = 201.1 sq"

201.1/$25.40 = 7.92 sq" per $1

That should suffice the calculations part..
now for the decisions..

on another note, just found this in my fridge

Goes well with coffee and vodka ~
