we know that
The surface area of a sphere is equal to
[tex]SA=4\pi r^{2}[/tex]
where
r is the radius of the sphere
in this problem we have
[tex]r=16\ units[/tex]
substitute in the formula
[tex]SA=4\pi(16^{2})[/tex]
[tex]SA=1,024\pi\ units^{2}[/tex]
or
[tex]SA=3,216.99\ units^{2}[/tex]
therefore
the answer is
[tex]SA=1,024\pi\ units^{2}[/tex]
