Answer:

2,122.64 square units or [tex]676 \pi[/tex] units squared

Step-by-step explanation:

The surface area of a sphere can be found using the formula [tex]A=4\pi r^2[/tex]. Since the radius is 13 units, substitute r=13.

[tex]SA=4\pi r^2\\SA = 4 \pi (13)^2\\SA = 4 \pi *169\\SA = 2122.64[/tex]

Without multiplying 3.14 for [tex]\pi[/tex], the answer is

[tex]SA = 169*4 \ pi\\SA = 676 \pi[/tex]
