Question

what is the area of a circle with a circumference of 43.98226 inches 3.14159 for π

Answer 1

\(\bf \underline{circumference}\textit{ of a circle}=2\pi r\qquad
\begin{cases}
circumference = &43.98226\\
\pi =&3.14159
\end{cases}
\\ \quad \\
circumference =2\pi r\implies \cfrac{circumference}{2\pi }=r
\\ \quad \\
\cfrac{43.98226}{2\cdot 3.14159}={\color{brown}{ r}}
\\ \quad \\ \quad \\
\underline{area}\textit{ of a circle}=\pi {\color{brown}{ r}}^2\)

Answer 2

once you get "r" or the radius
use that in the "area" equation
