The volume of cylinder = π * r * r * h = π * 4 * 4 = 50.26.
The volume of cone = 1/3* π * r * r * h = 0.333 * π * 4 * 1.5 = 6.27.
The volume of cylinder + volume of cone = 56.53.
The volume of cone = 1/3* π * r * r * h = 0.333 * π * 4 * 1.5 = 6.27.
The volume of cylinder + volume of cone = 56.53.

Volume = Volume of cylinder+Volume of cone = 56.53 m^3.

Please anyone tell me about how much liters of paint in use.

Amount of paint required is total surface of tank divided by the area paint covers in 1 l; worked out that comes to 26.4 l, had to refer to a site for knowing surface area of cone ;);
Also, for painting do we need to consider base surface of tank?

Volume of cylinder volume of cone = Total volume.
& you know very well :).

Engineering mechanics is good for us. That problem is very hard.

Surface area of cylinder = pi*d*height
3.14x4x4=50.2m2
Surface area of cone = pi*r*s
s=hyp of triangle s=sqr root(2^2+1.5^2)
s= 2.5m
pi*r*s = 15.7m2
total = 50.2+15.7=65.9m2
/2.5m2 = 26.4 liters of paint
3.14x4x4=50.2m2
Surface area of cone = pi*r*s
s=hyp of triangle s=sqr root(2^2+1.5^2)
s= 2.5m
pi*r*s = 15.7m2
total = 50.2+15.7=65.9m2
/2.5m2 = 26.4 liters of paint
