What is the surface area of a sphere with a radius of 16 units?
Formula of surface area of a sphere is 4\(\pi r^{2}\).
Hence it is 4\(\pi 16^{2} ≈ 3216.99 ≈3217\)
we know that
The surface area of a sphere is equal to
\(SA=4\pi r^{2}\)
where
r is the radius of the sphere
in this problem we have
\(r=16\ units\)
substitute in the formula
\(SA=4\pi(16^{2})\)
\(SA=1,024\pi\ units^{2}\)
or
\(SA=3,216.99\ units^{2}\)
therefore
the answer is
\(SA=1,024\pi\ units^{2}\)
