Answer:

[tex]2,486.88\ calories[/tex]

Step-by-step explanation:

step 1

Find the area of the pizza

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=12/2=6\ in[/tex]

substitute

[tex]A=(3.14)(6^{2})=113.04\ in^{2}[/tex]

step 2

we know that

A [tex]12-inch[/tex] diameter has [tex]22[/tex] calories per square inch

By proportion

Find how many calories are in the entire pizza

so

[tex]\frac{22}{1}\frac{cal}{\ in^{2}}=\frac{x}{113.04}\frac{cal}{\ in^{2}}\\ \\x=22*113.04\\ \\x=2,486.88\ calories[/tex]
