In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
Sphere:
diameter = 18 mm
volume = ?
Step 02:
Volume of a sphere
V = 4/3 π r³
r = d/2 = 18mm / 2 = 9mm
[tex]V\text{ = }\frac{4}{3}\pi(9\operatorname{mm})^3[/tex][tex]V\text{ = }972\text{ }\pi\text{ mm³}[/tex]
The answer is:
The volume of the sphere is 972 π mm³
