Answer: 3821.1 mm^3
Step-by-step explanation:
The volume of a sphere is calculated by the equation volume = (4/3) · π · r^3
Since r is the radius, we need to get radius by halving the diameter.
19.4 mm/2 is equal to 9.7 mm
Now, with substitution of variables(assuming pi is 3.14:
(4/3)(3.14)(9.7^3)
(4/3)(3.14)(912.673)
(4/3)(2865.79322)
3821.057627 mm^3 as the sphere's volume
Therefore, we have to now round our answer:
3821.057627 -----> 3821.1 mm^3
