The area of a circle with radius rr is given by:
$$\displaystyle{A}=\pi{r}^{{{2}}}$$
Substitute $$r=8$$ inches and use 3.14 for $$\pi$$ as instructed:
$$\displaystyle{A}={\left({3.14}\right)}{\left({8}\right)}^{{{2}}}$$
$$\displaystyle{A}={\left({3.14}\right)}{\left({64}\right)}$$
$$\displaystyle{A}={200.96}$$ square inches
