The formula for calculating the density of a sphere is density = mass / volume. This means that the density of a sphere is equal to the mass of the sphere divided by its volume.
To calculate the mass of a sphere, you need to know its density and volume. You can then use the formula mass = density x volume to find the mass. Alternatively, if you know the diameter and density of the sphere, you can use the formula mass = (4/3)πr^3 x density, where r is the radius of the sphere.
Yes, the density of a sphere can change if its mass or volume changes. For example, if more material is added to the sphere, its mass will increase, causing the density to increase. Similarly, if the volume of the sphere is increased, the density will decrease.
The units used to measure density depend on the system of measurement being used. In the metric system, density is typically measured in grams per cubic centimeter (g/cm^3). In the imperial system, it is measured in pounds per cubic inch (lb/in^3).
The diameter of a sphere does not directly affect its density. However, the diameter is used to calculate the volume of the sphere, which is a factor in the density formula. A larger diameter will result in a larger volume, which can lead to a lower density if the mass of the sphere remains the same.
