Given:

Diameter = 7 mm

π=3.14

To determine the sphere's volume, we use the formula:


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

where:

V=Volume

r=radius

(Note: radius = diameter/2)

Since the diameter is 7mm, the radius is:

radius = diameter/2 = 7/2 = 3.5mm

We plug in r=3.5 mm and π=3.14 into the sphere's volume formula.


\begin{gathered} V=(4)/(3)\pi r^3 \\ =(4)/(3)(3.14)(3.5)^3 \\ \text{Calculate} \\ V=179.5\text{ mm\textasciicircum{}3} \end{gathered}

Therefore, the answer is 179.5 mm^3.
