Geometry

 WORD PROBLEMS-GEOMETRY VOLUME  1. A square has an area of ​​sixteen square centimeters. What is the length of each of its sides?  The formula for the area A of a square with side length s is:  A = s 2  They gave me the area, so, plug this value into the area formula and see where this leads:  16 = s 2 4 = s ___________________________________________________ 2. A circle has an area of ​​49 square units. What is the length of the diameter of the circle?   The formula for the area A of a circle with radius r is:  A = (pi) r 2  the radius r is half the length of the diameter d, so: 49 pi = (pi) r 2 (49 pi) / pi = [(pi) r 2] / pi 49 = r 2 7 = r https://www.purplemath.com/modules/perimetr.htm 

  GEOMETRIC VOLUMEN EXAMPLES: https://www.splashlearn.com/math-vocabulary/geometry/volume  SHAPES                                                FORMULA Rectangular Prism:   Volume = l × w × h , where l is length, w is width and h is height. Cube:  Volume = a³  , where a is length of each side. sphere:   Volume = 4/3 πr³ , where r is the radius cylinder:  Volume = πr²h , where r is the radius and h is the height. cone:  Volume = 1/3 πr²h , where r is the radius and h is the height.  Volumes of Shapes: Definition & Examples - Video & Lesson Transcript | Study.com  

  GEOMETRY ✔ GEOMETRY DEF:  Geometry  is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things. Flat shapes like squares, circles, and triangles are a part of flat  geometry  and are called 2D shapes. GEOMETRY IT DIVIDES INTO TWO PARTS:  1. AREA: the  area  can be defined as the space occupied by a flat shape or the surface of an object. The  area  of a figure is the number of unit squares that cover the surface of a closed figure. 2. VOLUMEN:   volume  can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object. Here, the blocks and books take up space.  Volume  of basic solid  geometric shapes  like cubes and rectangular prisms can be determined using formulas. What is Volume?
