Mensuration Formulas Mensuration is the branch of mathematics which deals with the study of Geometric shapes, their area, volume and related parameters. Diameter A line segment through the centre of a sphere , and with the end points on the sphere is called the diameter of the sphere. When making a cake for example we may need tins of a specific width and length for a particular recipe. Slant height The slant height of a frustum of a right circular cone is the length of the line segment joining the extremities of two parallel radii , drawn in the same direction of the two circular bases. The figures that can be drawn on our note books or blackboards are called plane figures. This chapter will help the students to strengthen their foundation on Data Handling to deal with further complex topics meritoriously.

NextOr use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. To help their students in the proper way, school teachers and mathematics experts are giving good advice to the. She wants to construct a house in the middle of the plot. I am also grateful to my school for allowing me to used the library and internet facility at or according to my will and my teachers for their academic guidences and support. You can choose whether to allow people to download your original PowerPoint presentations and photo slideshows for a fee or free or not at all. With an in-depth study of this chapter and solving of the problems will help the students to solve complex problems easily.

NextIf we cut many of these plane figures of the same shape and size from cardboard sheet and stack them up in a vertical pile. The chapter begins with introduction to the concept of data through an analytical situation and gradually plunges into complex operations with data handling. It has six faces and all are squares and identical. Vertex For any two edges that meet at an end point , there is a third edge , that also meets them at that end point. However, for precise mensuration problems, the Euclidean distance must be used.

NextFor a small fee you can get the industry's best online privacy or publicly promote your presentations and slide shows with top rankings. How many such tiles are required to cover a floor of area 1080 m 2? And, best of all, most of its cool features are free and easy to use. In this chapter, we will try to solve problems related to perimeter and area of other plane closed figures like quadrilaterals. An equivalent condition is that opposite sides are parallel a square is a parallelogram , that the diagonals perpendicularly bisect each other, and are of equal length. Every student's dream is to score the good marks in the final board examination as the future of the student will depend on the result of these exams. Spherical shell The difference of two solid concentric spheres is called a spherical shell.

NextAxis The line segment joining the centers of 2 bases is called the axis of the cylinder. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides if they are not parallel; otherwise there are two pairs of bases. Most of the presentations and slideshows on PowerShow. We'll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides. There is truly something for everyone! An equivalent condition is that the diagonals perpendicularly bisect each other.

NextAccording to the news, the exam for the matriculation and intermediate schools will be held next year. We found the area and perimeter of various plane figures such as triangles, rectangles, circles etc. Area of a rectangle Area of a rectangle length x width Area length x width Area 5cm x 3cm Area 15cm² 11 On your white boards find the area of these rectangles 12 10cm 6cm 60cm² 13 2mm 24mm² 12mm 14 23km 2km 46km² 15 2m 82cm 1. We will also learn about surface area and volume of solids such as cube, cuboid and cylinder. It would never have been possible without the support of my parents.

NextSolid cuboid A solid cuboid or a cuboid or a cuboidal region in the part of space bounded by the size faces of a cuboid. Edges Any two adjacent faces of a cuboid meet in a line segment , which is an edge of the cuboid. Presentation Summary : Its techniques are used in all aspects of a vision system. Tools such as measuring jugs may be used to determine volumes. English is a global language, so it is very important to learn that subject as it can help. I also called this information from internet by using yahoo! Pictorial representation and graphical representation makes the chapter more interactive and clears the concepts in a better and comprehensive manner. Presentation Summary : Believed education should not be just for elite class.

NextWe may look at how to cut down the number of miles we have to travel by taking short cuts. Summary, Do Yourself Activities and Group exercises help the students to dive into the world of Numbers with a throttle and master the topic. In other words, parallelograms include all rhombi and all rhomboids, and thus also include all rectangles. Hope you like them and do not forget to like , social share and comment at the end of the page. Whether your application is business, how-to, education, medicine, school, church, sales, marketing, online training or just for fun, PowerShow. Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles.

NextA quadrilateral is a square if and only if it is both a rhombus and a rectangle four equal sides and four equal angles. Which field has a larger area? Rectangles include squares and oblongs. The board has also announced the date of the exams. Solid cube A solid cube is the part of the space enclosed by the size faces of the cube. Equivalent conditions are that opposite sides are of equal length; that opposite angles are equal; or that the diagonals bisect each other.
