As shown in the figure a cylindrical glass contains water a metal sphere of diameter 2 cm is immersed in it find the volume of the water.

Step 1
find the volume of a cylinder with height=30 cm

volume of a cylinder=pi*r²*h
r=14/2> r=7 cm
h=30 cm
so
volume =pi*7²*30> 4615.8 cm³

step 2
find the volume of a sphere
volume sphere=(4/3)*pi*r³
r=2/2> 1 cm
volume sphere=(4/3)*pi*1³> 418.67 cm³

step 3
find the volume of water

volume of water=volume of a cylinder-volume of a sphere
volume of water=4615.8-418.67> 4197.13 cm³
