If a circle has a radius of 4 inches, how many square feet is the area of half of the circle?

Hello,
I think you should first convert inches into feet.
Rhe area of a circle is given by the formula : $\displaystyle A=\pi R^2$ where R is the radius.
Hence the area of half the circle will be $\displaystyle A'=\pi \frac{R^2}2$
