Answer:

22 cubic millimeters.

Step-by-step explanation:

Given a sphere with radius, r:

$\text{Volume}=(4)/(3)\pi r^3$

If the sphere has a radius of 7/4 mm, then:

$\begin{gathered} V=(4)/(3)*(22)/(7)*\mleft((7)/(4)\mright)^3 \\ =(4)/(3)*(22)/(7)*(343)/(64) \\ =22.46\operatorname{mm}^3 \\ \approx22\operatorname{mm}^3 \end{gathered}$

The volume of the sphere is 22 cubic millimeters (to the nearest cubic millimeter).
