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?

We know that
the volume of a sphere=(4/3)*pi*r³
The gumball has a sphere shape

find the volume of one gumball
volume=(4/3)*pi*r³
radius r=6mm
volume=(4/3)*pi*6³> 288*pi mm³

volume of 4 gumball=4*288*pi> 1152*pi mm³> 3617.28 mm³

the answer is
1152*pi mm³  (3617.28 mm³)
