We have to find the area of a circle with a radius of 11 in.

We will use the formula for the area of a circle, that is:


A=\pi\cdot r^2

Then, replacing with r=11 and pi=3.14, we get:


\begin{gathered} A=\pi\cdot r^2 \\ A=3.14\cdot(11\text{ in})^2 \\ A=3.14\cdot121\text{ in}^2 \\ A=379.94\text{ in}^2 \end{gathered}

The area of a circle with radius 11 inches is A=379.94 sq in.
