Study Notes
Definition and Importance
- Mensuration is the process of measuring the perimeter, area, and volume of various geometric shapes and objects.
- It is an essential concept in mathematics, physics, engineering, and other fields where calculations of size and quantity are crucial.
Perimeter
- The perimeter of a shape is the distance around it.
- Formula: Perimeter = 2(Length + Width) for a rectangle
- Formula: Perimeter = π × Diameter for a circle
Area
- The area of a shape is the amount of space inside it.
- Formula: Area = Length × Width for a rectangle
- Formula: Area = π × Radius^2 for a circle
- Formula: Area = (Base × Height) / 2 for a triangle
Volume
- The volume of an object is the amount of space inside it.
- Formula: Volume = Length × Width × Height for a rectangular prism
- Formula: Volume = (4/3) × π × Radius^3 for a sphere
- Formula: Volume = (1/3) × Base × Height for a pyramid
Surface Area
- The surface area of an object is the total area of all its surfaces.
- Formula: Surface Area = 2 × (Length × Width + Length × Height + Width × Height) for a rectangular prism
- Formula: Surface Area = 4 × π × Radius^2 for a sphere
Real-World Applications
- Architecture: calculating the area and volume of buildings
- Engineering: designing and building bridges, roads, and other structures
- Physics: calculating the volume and surface area of objects in motion
- Everyday life: measuring rooms, furniture, and other objects
