circle does not have volume

water displacement
Divide the diameter by 2.
Wouldn't a circle-based pyramid look a lot like a cone ? If so, you could probably use the formula for the volume of a cone and get away with it.
First 'weigh" the ojbect on a scale. this gives the mass. 2nd use the water displacement method to find the volume. Then divide Density = mass / volume.

Use volume displacement method.
water displacement
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
Multiple the length by the width by the height
Divide the diameter by 2.

You will need the mass and volume of the block. To find mass, use an electronic balance. To find volume, use length x breadth x height. For irregular solid, use the water displacement method. The density is mass divided by volume.
You use pi to find volumes that include circles, as volume = area x depth, and the area of a circle always involves pi
Get a sample of the metal. Use a scale to find its mass. If it is shape is that of a rectangular solid (box) measure length, width, and height and multiply to find volume. If it is irregularly shaped, use the water displacement method to find its volume. Divide the mass by the volume to get the density.
Because it's the circumference of the top and bottom circle times the height plus two times the area of the circle.
