Given:
Diameter = 7 mm
π=3.14
To determine the sphere's volume, we use the formula:
![V=(4)/(3)\pi r^3](https://img.qammunity.org/2023/formulas/mathematics/high-school/zraet4fw93vx9gjz3iextthjo546ibcpwc.png)
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}](https://img.qammunity.org/2023/formulas/mathematics/college/int1b2ye91eprlzyo0zhboqfwsehwgvj7n.png)
Therefore, the answer is 179.5 mm^3.
