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 ea

Firdavs [7]

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:
$Vt = 3617.28 mm ^ 3$
