goldi's pizza place is known throughout the city. the small pizza has a 6-inch radius and sells for $9.75. the medium pizza sells for $12.00 and has an 8-inch radius. the large pizza has a 20-inch radius and sells for $16.50. what size has the most pizza edge per dollar?. and what is the circumference of that pizza?
----------------------
Small pizza DATA:
Circumference = 12(pi) in
Cost per dollar = 9.75/12pi = 0.2586267... dollars
----------------------
Medium pizza DATA:
Circum = 16pi in
Cost per dollar = 12.00/16pi = 0.238732... dollars
----------------------------
Large pizza DATA:
Circum = 40pi in
Cost per dollar = 16.50/40pi = 0.1313... dollars
----------------------------
Small pizza has the most edge per dollar.
That circumference is 12pi inches

C6=2*3.14*6=37.68 CIRCUMFRANCE OR 37.65/9.75=3.86 PER INCH.
C8=2*3.14*8=50.24 CIRCUMFRANCE OR 50.24/12=4.19 PER INCH.
C20=2*3.14*20=125.6 CIRCUMFRANCE OR 125.6/16.5=7.61 PER INCH.
