How to find the Volume and Area of Cylinders ? The volume of a cylinder can be calculated with the help of the radius and height of the cylinder. The volume of a cube = (14) 3 Or 14 x 14 x 14. To find the volume of a cube, the edge length is multiplied three times hence the following formula volume: The volume of a cube = s3 or s x s x s Where, S = the side of the cube.įind the volume of a cube with an edge length of 14. The total three-dimensional space occupied by a cube is known as its volume. Since Area of rectangle = Length x Width this means A = 6 x 2 thus A = 12 cm 2 Implementation : How to Calculate the area of the following rectangle The formula for calculating the area of a rectangle is as follows: ![]() The area of a rectangle is the easiest to find. Implementation: How to Calculate the area of a circle with a diameter of 20 inches. Where A = area, π = constant = 3.14 and d = diameter The area of a circle can also be calculated using the diameter when the radius is unknown with the following formula: A = (π/4) × d2. The Area of Circles with Diameter Values. Implementation: Find the perimeter of an equilateral triangle with a side of 9 units. Since an equilateral triangle has equal sides the sum is represented as 3a To calculate the perimeter of an equilateral triangle the sum of its three sides is calculated hence the formula is, P = 3a, Where, P = Perimeter, a = one side of the triangle. Perimeter and Area of Equilateral TrianglesĪ type of triangle whose all three sides are equal, as well as all the three angles, is equal to 60° each is known as an Equilateral Triangle. Implementation: Calculate the circumference of a circle with an 8 cm radius. To calculate the circumference of a circle the following formula is used:Ĭ = 2πr, Where, c = circumference, r = for radius and π = constant = 3.14 Implementation: Calculate the area of a circle with a radius of 15cm. To calculate the area of a circle the following formula is used:Ī = πr 2 Where, A = Area of the circle, π = constant = 3.14, r = radius Some of the examples of topics of geometry are explained below: This branch of mathematics lets us learn about different angles, transformations, and similarities in the figures. Geometry is the branch of mathematics that deals with shapes (Circle, triangle, rectangle, oval, square, etc.), angles, dimensions, and sizes of a variety of things that we experience in our daily life. The word Geometry is derived from the two ancient Greek words, “Geo” and “Metron” where Geo stands for Earth and Metron stands for measurements. 4th Grade Math Games- Free Online Material.3rd Grade Math Quizzes – Grade 3 math games. ![]()
