To calculate the surface area of a sphere, you have to use the following formula:
[tex]SA=4\pi r^2[/tex]Where "r" is the radius of the sphere.
We know that the diameter of the sphere is d = 60 inches and that the radius is half the diameter, then the radius can be determined as follows:
[tex]\begin{gathered} r=\frac{d}{2} \\ r=\frac{60}{2} \\ r=30in \end{gathered}[/tex]Once the radius is calculated, you can determine the surface area of the sphere:
[tex]\begin{gathered} SA=4\pi(30^2) \\ SA=4\pi\cdot900 \\ SA=3600\pi\approx11309.73in^2 \end{gathered}[/tex]The surface area of the sphere is 3600π in², expressed as a decimal value, the surface area is equal to 11309.73 in²
