Question

How many cubic inches of material do you need to make a solid rubber ball with diameter
of 3

Answer 1

What is asked in the problem is simply the volume of the solid rubber ball.

Step-By-Step:

The volume of sphere given the diameter may be calculated by,

V = πd^3 / 6

Substituting the given value of diameter,

V = (π x 3³) / 6 = 9π/2 or 14.14

Nonetheless, one needs approximately 14.14 in³ of material.

Answer 2

Explanation:

What we're looking for here is the volume of this ball, which is the volume of a sphere:

`V=(4)/(3)\pi  r^3`

If our diameter is 3, then the radius is 1.5:

`V=(4)/(3)\pi  (1.5)^3`

In terms of π, the solution is

`4.5\pi` which can also be expressed as
`(9\pi )/(2)`

Or if you have to multiply in the pi, the solution is

V = 14.14 cubic inches
