Question

Stacy hits the jackpot one day at the gumball machine. She puts in a quarter and gets 4 gumballs rather than 1. The radius of each gumball is 6 mm.What is the total volume of all 4 gumballs?

Answer 1

For this case, we can model the problem as the volume of a sphere.
By definition, the volume of a sphere is:

`V = (4/3) * (\pi) * (r ^ 3)`
Where,
r: radius of the sphere.
Since we have 4 gumballs, then the total volume is:

`Vt = 4V Vt = (4) * (4/3) * (\pi) * (r ^ 3)`
Substituting values we have:

`Vt = (4) * (4/3) * (3.14) * (6 ^ 3) Vt = 3617.28 mm ^ 3`
Answer:
the total volume of all 4 gumballs is:

`Vt = 3617.28 mm ^ 3`
