Next, slide the object into the water, let it settle at the bottom of the cylinder, and record the new water level measurement. Suppose I have an electrically charged ring. Notice that this circular region is the region between the curves: y=sqrt{r^2-x^2}+R and y=-sqrt{r^2-x^2}+R. The volume of a cylinder is the density of the cylinder which signifies the amount of material it can carry or how much amount of any material can be immersed in it. To find the volume of an irregular object using a graduated cylinder, start by adding water to a cylinder that can accommodate the size of the object and write down the measurement for the current water level. One easy way to get "nice" cross-sections is by rotating a plane figure around a line, also called the axis of rotation, and therefore such a solid is also referred to as a solid of revolution.For example, in Figure 3.13 we see a plane region under a curve and between two vertical lines \(x=a\) and \(x=b\text{,}\) which creates a . Whereas, to find the volumes of complicated shapes, one can use integral calculus. A metallic sphere of radius 4.2 cm is melted and recast into the shape of a cylinder of radius 6 cm.
