Cone
Introduction A cone has a curved surface at the bottom; therefore, it contains two surface areas that are total surface area is the total surface area covered by the cone, whereas the curved surface the area consists of the surface area covered by the curved surface, which is the surface area other than the bottom circular flat surface. A cone has a vertex or an apex and a slant height. In this tutorial, we will discuss cones, slant height, curved surface area, total surface area, and a few solved examples. Cones Cones are three-dimensional figures with a circular surface at ...
Read MoreCuboid
Introduction A cuboid is a solid shape or a three-dimensional shape in geometry. A cuboid is an 8 vertices, 12 edges, and 6 rectangular faces convex polyhedron. A cuboid is also known as a rectangular prism. An example of a cuboid in the real world is a rectangular box. What is cuboid? Imagine a shape that results from stacking numerous congruent rectangles on top of one another. The resultant shape is known as a cuboid. Dimensions of a Cuboid In order to describe the length, width (breadth), or height of an edge of a cuboid shape, it should be ...
Read MoreDiagonal Matrices
Introduction A diagonal matrix is a matrix in which the entries outside the main diagonal are all zero. Matrices are used in practical life events like military parades, school parades, and planting. The concept of matrix and determinant is recorded as having appeared in the fourth century B.C, although its use is thought to have begun only in the second century BC. Then, towards the end of the seventeenth century, the concept of matrix and determinants came back into use. Mathematical models of everyday world problems are formed as sets of linear equations. Matrices are essential and inevitable to solve ...
Read MoreArea of Quadrilateral
Introduction Area of a quadrilateral is the region enclosed by the sides of the quadrilateral. The quantity of territory contained within a quadrilateral determines its area. Let's review the definition of a quadrilateral. A closed shape with four line segments enclosing it is referred to as a quadrilateral. Both regular and irregular quadrilaterals exist. A quadrilateral with regular sides is one with equal-length sides. An irregular quadrilateral is a quadrilateral that is not regular. There are six different kinds of quadrilaterals. Square, rectangle, parallelogram, trapezoid, rhombus, kite, etc. In this tutorial, we discuss areas of all these quadrilaterals. We'll ...
Read MoreArea
Introduction Area is the space occupied by a figure. Polygons are the two-dimensional shape which has plane closed figures made of the line segments. Based on the number of sides each name of the polygon varies such as, triangles, quadrilateral, etc. The circle and ellipse are closed two dimensional shapes that have no sides. Area is a two-dimensional measurement that represents the amount of space covered by a two-dimensional shape. Area Area is the space inside a 2D shape. To measure the area of polygons, when the figure is in the grid, we can use unit squares. By ...
Read MorePaired T-Test
Introduction The paired t-test in statistics is a tool that compares the data between two groups of samples and determines whether the mean difference between given measurements is zero or not. In statistics, two-sample t-tests are tools used to compare the means of two datasets. These tests are also known as Student’s t-tests, The results from the tests are used to evaluate the difference between the mean of two samples. The difference is not likely to be due to sampling error or by chance. Paired t-test is used to compare means of two datasets where we are made available with ...
Read MoreApplication Of Linear Graphs
Introduction The applications of linear graphs are widely seen in day-to-day life. Graphs in the form of a straight line Ax+By+C=0 are called Linear graphs. In the standard form of line equation, A and B are coefficients, x and y are variables and C are a constant. In simple terms, a linear graph is a representation of the relationship between two or more variables. By plotting the variables of the equation or say the points x, y, z, etc., on a graph we get a straight line. The applications of linear graphs are widely seen in analysing and ...
Read MoreApplications of Decimal in Daily Life
Introduction Applications of decimals in daily life are in the field of science , engineering, commerce and finance. A Decimal system is a numeral system containing integer numbers and non-integer numbers. The application of the decimal system is widely used in our day-to-day life. Decimal system provides values more accurately than the whole numbers. A Scottish Mathematician John Napier was the first one to introduce the decimal system. Denoting numbers in a decimal system is called Decimal notation.Sometimes the amount of money we get as income from various sources, the electricity bill, weight and height of both living ...
Read MoreDifference between Cube and Cuboid
Introduction The difference between a cube and a cuboid is that a cube has six identically sized square faces while a cuboid has rectangular faces . Only the cuboid and the cube are two such solids that have certain shared qualities, such as each having six faces, eight vertices, and twelve edges. There are numerous shapes in geometry, such as cylinders, spheres, and cones, that have distinct properties. Additionally, all inside angles are 90 degrees. In this tutorial, we will discuss the difference between Cube and a Cuboid. Polyhedrons Polyhedrons are 3D shapes with straight edges, flat faces, straight edges, ...
Read MoreDistance Formula
Introduction Distance formula used to find the distance measure between two lines . In an XY-plane or Cartesian plane, the length of a line joining any two coordinates on the plane can be determined by subtracting them. The coordinates are different depending on their position on the XY plane. To find the distance between the two points $\mathrm{P(x_{1}\, \:y_{1})\:\&\:Q(x_{2}\, \:y_{2})}$ on the coordinate axis we apply the distance formula. To find the perimeter or the length of the sides of any two-dimensional geometric figures we use the distance formula. The distance formula has a wide range of real-life applications such ...
