we know that

The volume of the sphere is equal to


V=(4)/(3)\cdot\pi\cdot r^3

In this problem we have

r=14/2=7 in ----> the radius is half the diameter

pi=3.14

substitute the given values


\begin{gathered} V=(4)/(3)_{}\cdot(3.14)\cdot(7^3) \\ V=1,436.0\text{ in\textasciicircum{}3} \end{gathered}

answer is 1,436.0 cubic inches
