Calculate the volume of the cylinder that is filled. Then subtract the volume of the marbles. You will then have the volume of the water.

$$v = pir^2h$$
where V = colume
pi = 3.1415
r = d/2 = 6/2 =3
h = 12
v =pi*9*12
v =108 pi

same with marbles
but those are spheres
v = 4pir^3/3
6v = 24pi/3
6v = 8pi
Vf = V cylinder  - V marbles
Vf = 100pi
Vf  =314,15

oh wow thank you ! its 108 right?

p0sitr0n · Answer

100*pi = 314.15

p0sitr0n · Answer

you have to substract the marbles
