From the question
A pepperoni pizza has a radius of 10 inches
A pizza is in a circle shape then area of circle (A) is given as
[tex]A=\pi r^2[/tex]r = 10 inches
Hence we have
[tex]\begin{gathered} A=\frac{22}{7}\times10in\times10in \\ A=\frac{22}{7}\times100in^2 \\ A=3.142\times100in^2 \\ A=314.2in^2 \end{gathered}[/tex]Therefore, the area of the pepperoni pizza is 314 inches squared
