displacement
Volume=(pi)(radius^2)(height)
The volume of a rectangle is 0. It is a 2-dimensional object and so has no volume.
circumference is the perimeter of a circle. a circle is 2 dimensional. volume is 3 dimensional. you need to state what shape it is. I could guess that you are talking about a cylinder. the volume is pi.r2.h, if you find the radius from the volume, you can find the perimeter of the circle by 2.pi.r
Hemisphere volume = [(4 / 3) πr3] / 2
displacement
The volume of an odd size rock can be obtained through methods like displacement method.
This density is measured by several methods; the simplest is with the formula density=mass/volume.
Volume=(pi)(radius^2)(height)
There are two questions in your question. Question #1: How do you find the density ? Answer #1: Divide the mass by the volume. And this time, don't forget to include the units. Question #2: Find its volume ? Answer #2: 0.25
The volume of a rectangle is 0. It is a 2-dimensional object and so has no volume.
A gallon is a measure of volume. Volume can be measured by using one of the 2 most common methods: water displacement or a graduated cylinder.
circumference is the perimeter of a circle. a circle is 2 dimensional. volume is 3 dimensional. you need to state what shape it is. I could guess that you are talking about a cylinder. the volume is pi.r2.h, if you find the radius from the volume, you can find the perimeter of the circle by 2.pi.r
Find the density of a material that has a mass of 2 kg and a volume of 5 m3.
volume=1/2*length*width*height.
Hemisphere volume = [(4 / 3) πr3] / 2
Calculate the volume of a full sphere, then divide that by 2.
