How To Figure Cost Per Square Inch Of Pizza 13 Steps

For example, if you are ordering a 20 inch pizza, calculate 20÷2=10{\displaystyle 20\div 2=10}. So the radius of the pizza is 10 inches.

For example, if the radius is 10 inches, your formula will look like this: A=π(102){\displaystyle A=\pi (10^{2})}.

For example, if the radius is 10 inches, you would calculate 10×10=100{\displaystyle 10\times 10=100}, so your formula will now look like this: A=π(100){\displaystyle A=\pi (100)}.

For example:A=π(100){\displaystyle A=\pi (100)}A=3. 14(100){\displaystyle A=3. 14(100)}A=314{\displaystyle A=314}So, the area of a 20-inch round pizza is 314 square inches.

For example, if a pizza costs $32 and has an area of 314 square inches, you would calculate 32÷314=. 101{\displaystyle 32\div 314=. 101}. So, the cost per square inch of pizza is about . 10, or 10 cents.

For example, you might want to find the value of a square 16-inch pizza. Both the length and the width will be 16 inches.

For example, for a square 16-inch pizza, your formula will look like this: A=16×16{\displaystyle A=16\times 16}.

For example:A=16×16{\displaystyle A=16\times 16}A=256{\displaystyle A=256}So, the area of a square 16-inch pizza is 256 square inches.

For example, if a pizza costs $32 and has an area of 256 square inches, you would calculate 32÷256=. 125{\displaystyle 32\div 256=. 125}. So, the cost per square inch of pizza is about . 13, or 13 cents.
