***
r=radius of cylinder
letv=original volume of water in cylinder
let h=height of water level in cylinder
volume of water in cylinder=cross-section area of cylinder*depth of water
v=πr^2*h=π*100*15=1500π cm^3
new volume=1500π+900
h=(1500π+900)/πr^2=(1500π+900)/100π=(15+9/π)=17.86
what is the height that the water level rises in cm? 17.86
