Answer:
V = 21145.01 mm³
Step-by-step explanation:
Given that:
The radius of the gumball = 30 mm
The radius of the spherical hollow-core = 28 mm
Consider the radius of the gumball to be [tex]r_2[/tex] and the radius of the spherical hollow-core to be [tex]r_1[/tex]. Then;
The volume of the gumball can be determined by using the formula of a sphere.
[tex]V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)[/tex]
[tex]V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)[/tex]
V = 21145.01 mm³
