I have a question i am stuck on please could any one help
A solid cylinder 350mm in diameter and of total length 750mm floats upright in fresh water to a deoth of 500mm. (Need working out)
Determine the density of the material in the cylinder

The cylinder displaces an amount of water that weighs the same as itself.
The water displaced fits into a cylinder with diameter 350mm and height 500mm, which has 2/3 the volume of the cylinder in the question.
Water has density 1000 kg/m³, so for the weights to match, the cylinder must have density ~667 kg/m³.
Why did the vector cross the road?
It wanted to be normal.

Thanks but could you tell me what equation you used to find the answer please

Density=Mass/Volume
Volume of cylinder=πr²h where π= pi (3.141.....), r= radius, and h= height
Hope that helps.
