how many cubic inches of material do you need to make a solid rubber ball with diameterof 3
Accepted Solution
A:
Answer:Step-by-step explanation:What we're looking for here is the volume of this ball, which is the volume of a sphere:[tex]V=\frac{4}{3}\pi r^3[/tex]If our diameter is 3, then the radius is 1.5:[tex]V=\frac{4}{3}\pi (1.5)^3[/tex]In terms of π, the solution is[tex]4.5\pi[/tex] which can also be expressed as [tex]\frac{9\pi }{2}[/tex]Or if you have to multiply in the pi, the solution isV = 14.14 cubic inches
