The last example we will provide in this section is one for volume. The volume of regular solids such as spheres, cylinders, cones and rectangular prisms are known. We will find an expression for the volume of a cylinder, which is defined as V=πr2hV=πr2h....
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a gra...
A pyramid is a solid with a polygon base and connected by triangular faces to its vertex. The lateral faces meet at a common vertex. The height of the pyramid is the perpendicular distance from the base to the vertex. A pyramid is a regular pyramid if its base is a regular polygon and...
A straight length of circular pipe has an internal diameter of 2cm and a length of 1.7m. Calculate the volume of water in the pipe. In this example you need to calculate the volume of a very long, thin cylinder, that forms the inside of the pipe. The area of one end can be calcula...
Answer to: The shaded pyramid in the diagram is cut from a rectangular solid. How does the volume of the pyramid compare with the volume of the...
The volume of a solid right circular cone is {eq}11088 \, \, cm^3 {/eq}. If its height is 24 cm then find the radius of the cone. Cone The cone is a solid generated by the revolution of a right-angled triangle about one of the s...
Alternatively, the plate 1 may be slidably mounted. The scales may be interchanged as between the plates 1 and 7. The invention is applicable to articles of any regular and uniform cross-section.
Volumes of some simple shapes, such as regular, straight-edged and circular shapes can be easily calculated using arithmetic formulas. More complicated shapes can be calculated by integral calculus if a formula exists for its boundary. The volume of any shape can be determined by displacement. -...
Rectangular solid (volume of a box) = lwhlwh, where ll is the length, ww is the width and hh is the height (a simple pool may serve as an example of such shape). Pyramid = (1/3)Ah(1/3)Ah where AA is a base area and hh is the height. For a pyramid with a regular base,...
