Answer»

Given,For upper cylinderHeight h1 = 10 cmDiameter = 10 cm, Radius r1 = 5 cm

For lower cylinderHeight h2 = 10 cmDiameter = 20 cm, Radius r2 = 10 cm

Then,Volume of upper cylinder= pi*r1^2*h1= 22/7*(5*5)*10= 22*250/7= 785.7 cm^2

Volume of lower cylinder= pi*r2^2*h2= 22/7*(10*10)*10= 22000/7= 3142.85 cm^2
