Hi
I have a problem I want to find the mass of a hollow cylinder which is made of steel, the sylinder diameter is 2.5m, the length is 4m, then I have done my calculations as follow:
Volume of the cylinder = Лd²/4 x h = 19.635 cubic meters
Mass of cylinder = volume x denisity
= 19.635 x 7800 = 153153 kg
This a very big mass I think it's wrong but I don't know why if you know can you help me please?
