Answer:
\(2,486.88\ calories\)
Step-by-step explanation:
step 1
Find the area of the pizza
The area of a circle is equal to
\(A=\pi r^{2}\)
we have
\(r=12/2=6\ in\)
substitute
\(A=(3.14)(6^{2})=113.04\ in^{2}\)
step 2
we know that
A \(12-inch\) diameter has \(22\) calories per square inch
By proportion
Find how many calories are in the entire pizza
so
\(\frac{22}{1}\frac{cal}{\ in^{2}}=\frac{x}{113.04}\frac{cal}{\ in^{2}}\\ \\x=22*113.04\\ \\x=2,486.88\ calories\)
