Solution ✌️✌️
R=2m=200cm
h=10cm
r=10cm
now...
volume of the cylinder of radius R and height h is
V1=πR²h
and volume of a hemisphere of radius r is
V2=2πr³/3
now...
therefore...
number of such hemispheres.....=V1/V2
noww ...
=>V1/V2=3R²h/2r³
=>V1/V2=(3×200²×10)/(2×10³)
=>V1/V2=600
therefore the number of students=600
