Formula Math Perimeter of a Circle

Perimeter is the distance around a closed figure and is typically measured in millimetres (mm), centimetres (cm), metres (m) and kilometres (km). These units are related as follows: 10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km The word 'perimeter' is also sometimes used instead of circumference. If we know the radius Given the radius of a circle, the circumference or perimeter can be calculated using the formula bwloe: Perimeter (P) = 2 · π · R where: R is the radius of the circle π is Pi, approximately 3.142If we know the diameter If we know the...

Formula Math Perimeter of a Rectangle

Formula Math in rectangle, the distance around the outside of the rectangle is known as perimeter. A rectangle is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units such as feet or meter etc.The perimeter of a rectangle is the total length of all the four sides. Perimeter of rectangle = 2L + 2W. Math Example 1 : Rectangle has the length 13 cm and width 8 cm. solve for perimeter of rectangle. Smart Solution: Given that: Length (l) = 13 cm Width (w) = 8 cm Perimeter of the rectangle = 2(l + w)...

Formula Math Surface Area of a Sphere

Difinition smart math formula of A sphere is a three-dimensional space, such as the shape of a football. A sphere is a body bounded by a surface whose every point is equidistant (i.e. the same distance) from a fixed point, called the centre or the origin of the sphere. Like a circle in three dimensions, all points from the center are constant. The distance from the center to any points on boundary is known as the radius of the sphere. The maximum straight distance through the sphere is known as the diameter of the sphere. One-half of...

Formula Math Volume of a Cuboid

Smart Math formula Volume of a Cuboid In geometry, a cuboid is a solid shaped figure formed by six faces. There are two definitions for a cuboid. In the more general definition of a cuboid, the only supplementary condition is that each of these six faces is a quadrilateral. Otherwise, the word “cuboid” is sometimes used for referring a shape of this type in which each of the faces is a rectangle, and in which each pair of adjacent faces meets in a right angle.  A cuboid with length l units, width w units and height h units...

Surface Area of a Cuboid Formula Math

The total surface area (TSA) of a cuboid is the sum of the areas of its 6 faces, which is given by: TSA = 2 (lw + wh + hl) Remember the surface area is the total area of all the faces of a 3D shape. The lateral surface area of a cuboid is given by: LSA = 2 (lh + wh) = 2 h (l + w) Smart Math Formula in aplication : Find the total surface area of a cuboid with dimensions 8 cm by 6 cm by 5 cm. TSA = 2 (lw + wh + hl) TSA = 2 (8*6 + 6*5 + 5*8) TSA = 2 (48 + 30 + 40) TSA = 236 So, the total surface area of this cuboid is 236 cm2. Find...
