#### Objective of the Area Related to Circles

To find the circumference, area of a circle and circular paths. To derive and understand the formulae for perimeter and area of a sector of a circle. To find the perimeter and the area of a sector, using the above formulae. Finding the areas of some combinations of figures involving circles, sectors as well as triangles, squares, rectangles and solve daily life problems based on perimeters and areas of various plane figures.

##### Formulae for perimeters and areas

Perimeter of a rectangle = 2 (length + breadth)

Area of a rectangle = length × breadth

Perimeter of a square = 4 × side

Area of a square = (side) × (side)

Area of a parallelogram = base × corresponding altitude

Area of a triangle = 1/2 × base × corresponding altitude

Area of a rhombus = 1/2 × product of its diagonals

Area of a trapezium = 1/2 × (sum of the two parallel sides) × distance between them

Circumference of a circle = 2 × π × radius

Area of a circle = π × (radius) × (radius)

Area of a sector = angle/360 × π × (radius) × (radius)

Length of an arc = angle/360 × 2π × (radius)

Perimeter of a sector = angle/360 × 2π × (radius) + 2(radius)

Area of segment = Area of sector – area of triangle

###### Historical Facts!

1. All the mathematical ideas have emerged out of daily life experiences. The first ever need of human being was counting objects. This gave rise to the idea of numbers. When the man learn to grow crops, following types of problems had to be handled:

Fencing or constructing some kind of a boundary around the field, where the crops were to be grown.

2. Allotting lands of different sizes for growing different crops.

3. Making suitable places for storing different products grown under different crops.

4. These problems led to the need of measurement of perimeters (lengths), areas and volumes, which in turn gave rise to a branch of mathematics known as Mensuration. Area related to circle is one of the part of mensuration.
