The question is asking to calculate the density of the steel ball-bearing using its given circumference and weight. First, we need to find the radius of the ball-bearing from its circumference. The formula for the circumference (C) of a circle is C = 2πr, where r is the radius. We rearrange the formula to solve for r: r = C / (2π).
Density Calculator
However, when regarding gases, density is largely affected by temperature and pressure. An increase in pressure decreases volume, and always increases density. Increases in temperature tend to decrease density since the volume will generally increase. There are exceptions however, such as water's density increasing between 0°C and 4°C.
