A disco ball is shaped like a sphere with a diameter of 16 inches. To the nearest square inch, what is the surface of the disco

Mademuasel [1]

If the diameter is 16 inches, then its radius is half that, r = 8.

$\bf \textit{surface area of a sphere}\\\\
A=4\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
r=8
\end{cases}\implies A=4\pi 8^2$
