campbell_st · Answer

find the volume of the cylinder, but first get the radius. 

$$V = \pi r^2 h $$

find the volume of 3 spherical marbles... but first find the radius of the marbles. 

$$V = 3 \times \frac{4}{3} \pi r^3$$

the volume of water will be 

Volume of the cylinder x the volume of 3 marbles.

oops Volume of Water = Volume of Cylinder - Volume of the marbles... 

sorry about the typo
