Answer & Step-by-step explanation:
The formula for the volume of a sphere is:
[tex]V=\frac{4}{3} \pi r^3[/tex]
r is the radius, and it is cubed because this is a 3-D figure. Insert the values:
[tex]V=\frac{4}{3}(12)^3\pi[/tex]
Simplify the exponent ([tex]x^3=x*x*x[/tex]):
[tex]V=\frac{4}{3}(1728)\pi[/tex]
Simplify the fraction:
[tex]V=\frac{4*1728\pi }{3}[/tex]
[tex]V=\frac{6912\pi }{3}[/tex]
[tex]V=2304\pi \\\\or\\\\V=7238.2[/tex]
