Here are some of the important formulas for mensuration in mathematics:
- Area of a Circle: πr2, where r is the radius of the circle. The formula for finding the area of a circle is π times the radius squared. For example, if the radius of a circle is 5 cm, then the area would be 25π square cm.
- Circumference of a Circle: 2πr, where r is the radius of the circle. The formula for finding the circumference of a circle is 2 times π times the radius. For example, if the radius of a circle is 5 cm, then the circumference would be 10π cm.
- Area of a Rectangle: l x b, where l is the length and b is the breadth of the rectangle. The formula for finding the area of a rectangle is the product of its length and breadth. For example, if the length of a rectangle is 6 cm and its breadth is 4 cm, then the area would be 24 square cm.
- Perimeter of a Rectangle: 2(l + b), where l is the length and b is the breadth of the rectangle. The formula for finding the perimeter of a rectangle is 2 times the sum of its length and breadth. For example, if the length of a rectangle is 6 cm and its breadth is 4 cm, then the perimeter would be 20 cm.
- Area of a Square: s2, where s is the side of the square. The formula for finding the area of a square is the side squared. For example, if the side of a square is 5 cm, then the area would be 25 square cm.
- Perimeter of a Square: 4s, where s is the side of the square. The formula for finding the perimeter of a square is 4 times the side. For example, if the side of a square is 5 cm, then the perimeter would be 20 cm.
- Area of a Triangle: (1/2)bh, where b is the base and h is the height of the triangle. The formula for finding the area of a triangle is (1/2) times the base times the height. For example, if the base of a triangle is 6 cm and its height is 4 cm, then the area would be 12 square cm.
- Volume of a Cube: s3, where s is the side of the cube. The formula for finding the volume of a cube is the side cubed. For example, if the side of a cube is 5 cm, then the volume would be 125 cubic cm.
- Volume of a Rectangular Prism: l x b x h, where l, b and h are the length, breadth and height of the rectangular prism respectively. The formula for finding the volume of a rectangular prism is the product of its length, breadth, and height. For example, if the length of a rectangular prism is 6 cm, its breadth is 4 cm, and its height is 5 cm, then the volume would be 120 cubic cm.
- Volume of a Sphere: (4/3)πr3, where r is the radius of the sphere. The formula for finding the volume of a sphere is (4/3) times π times the radius cubed. For example, if the radius of a sphere is 5 cm, then the volume would be (4/3) x π x 125 cubic cm.
- Surface area of Sphere: 4πr2, where r is the radius of the sphere. The surface area of a sphere is the total area of its outer surface. It is equal to four times the area of a great circle of the sphere, which is a circle that passes through the center of the sphere and has the same diameter as the sphere. For example: Suppose the radius of a sphere is 5 cm. Surface area = 4πr2 = 4π x 52 = 4π x 25 = 100π square cm. So, the surface area of the sphere with a radius of 5 cm is 100π square cm.
