Given: A sphere with a radius of 4 ft.
Required: To determine the volume of the sphere.
Explanation: The volume of a sphere is given by the formula-
[tex]V=\frac{4}{3}\pi r^3[/tex]
Substituting the value of the radius, r=4 into the formula as-
[tex]V=\frac{4}{3}\times3.14\times4^3[/tex]
Further solving-
[tex]\begin{gathered} V=267.946\text{ ft}^3 \\ \approx267.95\text{ ft}^3 \end{gathered}[/tex]
Final Answer: The volume is about 267.95 cubic feet.
