The formula to calculate the volume of a sphere is:
[tex]V=\frac{4}{3}\pi\cdot r^3[/tex]
Start by finding the radius using the diameter and dividing it by 2
[tex]\begin{gathered} r=\frac{D}{2} \\ r=\frac{2}{2} \\ r=1ft \end{gathered}[/tex]
then, replace the radius in the formula and find the volume
[tex]\begin{gathered} V=\frac{4}{3}\cdot\pi\cdot r^3 \\ V=\frac{4}{3}\cdot\pi\cdot(1)^3 \\ V=\frac{4\pi}{3} \end{gathered}[/tex]
