Let us see about the learning one dimension. Dimension is a minimum number of co-ordinates that need to be defining the each point of an object or space is informally defined. The high dimensional spaces are occurring only in the math. The dimension of the shapes has the fundamental property in mathematics. Learning about the coordinates. The co-ordinates of the shapes are important to define the any type of vectors. The vector dimension space is the number of vectors used in the basis of space.The algebraic dimension is differing from the notion of the dimension. -Source Wikipedia. New dimensional learnning shape: Learning the shapes of new dimension which are given as follow: Line: Line is the one dimensional shape. Lines not having an end. so these are known as infinite. A collection of points are said to be a line. If any two points on the line is the defined as the section of line means then it is called a line segment. The one dimension of line can be classified into following types. Horizontal line Vertical line Transversal line Horizontal line: A line which is parallel to the x axis then the line is said to be horizontal. Vertical line: A line which is parallel to y axis then it is said to be vertical. Transversal line: The set of lines are intersected by a single line is known as the transversal line. Examples of new dimension learning: More about the one dimensional shape Line Segments: If any two points are connected on the line is called the line segment. A part of a line between the end points is named as line segments. It has two separate end points so we cannot enlarge it forever. The line segment can be denoted the arrow heads over the line 1. Perpendicular line segment 2. Parallel line segment Perpendicular line segment-It is a line which intersects at right angle. Parallel line segment-If two lines does not intersect at same plane. Some Examples for learning new dimensions and its shapes Learning One dimensional shape: Line Learning Two dimensional shapes: square, rectangle, parallelogram, rhombus. Learning Three dimensional shapes: Pyramid Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns,formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. (Source - Wikipedia) Some of the main branches of mathematics are algebra,geometry and calculus. There are number of project review questions available in various branches of mathematics. In this article, project review questions for circles are given. Project review questions on circles Area of circle: Formula: Area of a Circle = `pi` r2 r ---> radius Project review questions with solutions: 1)The radius of a circle is 12 inches. Find its area. Solution: Area of a Circle = `pi` r2 = 3.14 (12)2 = 3.14(144) = 452.16 in2 2)The radius of a circle is 18 inches. Find its area. Solution: Area of a Circle = `pi` r2 = 3.14 (18)2 = 3.14(324) = 1017.36 in2 Circumference of Circle: Formula: The Circumference of a circle can be calculated using the following formula: Circumference = 2 `pi` r or `pi`d where r ----> radius of circle d ----> diameter of circle , r = d/2 Project review questions with solutions: 1) Find the Circumference of a circle with radius 41 cm. Solution: Circumference of circle = 2 `pi` r = 2 (22/7) 41 = 2 (3.14) 41 = 257.48 cm 2) Find the Circumference of a circle with diameter 73 in. Solution: Circumference of circle = `pi` d = (22/7) 73 = (3.14) 73 = 229.22 in Practice problems for project review questions: Questions: 1)The radius of a circle is 17 inches. Find its area. 2)The radius of a circle is 21 cm. Find its area. 3) Find the Circumference of a circle with radius 22 in. 4) Find the Circumference of a circle with radius 8 cm. Answer key: 1) 907.46 in2 2) 1384.74 cm2 3) 138.16 in2 4) 50.24 cm2 Learn more on about Properties of Real Numbers and its Examples.
