ANSWER:
1809.5 square centimeters
STEP-BY-STEP EXPLANATION:
We have that the surface area of a sphere is given by the following equation:
[tex]A_s=4\cdot\pi\cdot r^2[/tex]
We know the radius of the sphere, therefore we replace:
[tex]\begin{gathered} A_s=4\cdot3.1415\cdot12^2 \\ A_s=1809.504\cong1809.5 \end{gathered}[/tex]
Therefore, the surface area is 1809.5 square centimeters.
