1)
total surface area =CSA of cylinder+CSA of 2hemisphere
=CSA of cylinder+CSA of sphere
=2πrh+4πr^2
=2πr(h+2r)
=2×22/7×5/2(9+2×5/2)
=22/7×5(9+5)
=110/7×14
=110×2
=220 mm
=22 cm
OR
hight of cone = h=2 cm
hight of cylinder= H = 12-4=8 cm
total volume=volume of cylinder+volume of two cone
=π r^2H+2×1/3πr^2h
=πr^2(H+2/3h)
=22/7×15/10×15/10(8+2/3×2)
=99/14×28/3=66 cm^3
