volume of water = volume of cylinder - six times volume of spheres

anonymous · Answer

4/3* PI* R cubed

experimentx · Answer

put R = 2 you get the volume of sphere.


also find the volume of cylinder with R=6 and H=10

experimentx · Answer

and
volume of water = volume of cylinder - six times volume of spheres

experimentx · Answer

gotta go ...
