Mensuration is a branch of mathematics that deals with the measurement of areas and volumes of various geometrical figures. Figures such as cubes, cuboids, cylinders, cones and spheres have volume and area. Mensuration deals with the development of formulas to measure their areas and volumes.Know More
The area of a cube is obtained using the formula A = 4 x length squared. The volume of a cube is obtained using the formula V = length cubed.
The area of a cuboid is obtained using the formula A = 2 [lb + lh + bh] where l is the length, b is the breadth and h is the height of the cuboid. The volume of the cuboid is arrived at using the formula V = length x breadth x height.
The curved surface area of a right circular cylinder can be obtained using A = 2πrh where h is the height of the cylinder and r is the radius of the base of the cylinder. The total surface area of the cylinder is obtained using A = 2πr [h+r], and the volume is arrived at using V = πr2h.
A cone has a curved surface area called the lateral surface area. The volume of a cone is one-third the volume of a cylinder with the same height and radius of the base.
Area is expressed in square units, while volume is expressed in cubic units.Learn more about Geometry
Plane geometry is the sub-category of geometry that deals with flat surfaces and the coordinates, lines and shapes on them. To draw a plane, use grid or graphing paper and a straight edge or measuring tool.Full Answer >
A cylinder technically has two curved edges, but in mathematics, an edge is defined as a straight line. Therefore, a cylinder actually has no edges, no vertices and two faces.Full Answer >
In mathematics, write indirect proofs by first assuming the opposite of the statement to be proven to be true. Then, try to prove the opposite of one of the given facts based on that assumption. Rather than directly proving something to be false, indirect proofs work by proving that something cannot be true, therefore, it must be false.Full Answer >
In mathematics, translation means moving an object from one location to another. It is a term often used in geometry. In translation, the object is moved without rotating, reflecting or resizing it.Full Answer >
