About 380.13 inches, or 121π
A 14-inch pizza with 1 and 1/2 inches of crush around it has a total of 3" taken off the diameter, leaving the actual amount of pizza covered a circle with a diameter of 11" (14 - 3).
To solve for the area of a circle, you calculate [tex]A = \pi r^2[/tex]. Plug in 11 for the radius to get [tex]A = 121 \pi [/tex]. This, when put into a calculator, results in about 380.13 square inches of a 14" that is actually covered if 1 1/2" around is crust.
