Given :
Diameter of the flask = 25 cm
radius, r =
cm
Height of the flask, h = 40 cm
We have to find out the volume of the cylinder flask
Volume 

= 
= 
Now calculate the volume of the marble
Given :
Diameter = 13 mm
radius, R 
Therefore, volume of the marble 


or 
Therefore, the number of the marbles 

= 170.68
Therefore, the number of the marbles used is approximately 170.
