To determine which size gives more pizza find the areas of each of the pizzas.

20 inch pizza (r=10):


\begin{gathered} A=\pi\cdot r^2 \\ A=\pi\cdot(10)^2 \\ A=100\pi \end{gathered}

12 inch pizza (r=6):


\begin{gathered} A=\pi\cdot r^2 \\ A=\pi\cdot(6)^2 \\ A=36\pi \\ Ap=2\cdot36\pi=72\pi \end{gathered}

20 inch pizza gives more pizza than 2 12 inch en el local normalito.

The answer is B. The blank must be filled this way:
