RS Aggarwal Solutions Class 7 Maths Chapter 20 Ex 20.6 – Overview

In the sixth exercise of RS Aggarwal Solutions Class 7 Maths Chapter 20, you will find 8 questions which is based on the questions of the area of the circle and the area of the circumference with an increased difficulty level.

Important Formulae

A. Area of the circle

A = π r²

Here,

A = Area of the circle

r = The Radius of the circle

B. Area of Semi-Circle

We can define the total area of the semi-circle as the exact region taken by that same semi-circle in a 2-dimensional plane. The area of a semi-circle is equivalent to half of the circle’s area, where the radius is always equal.

Henceforth, Area of the Semi-Circle = { ( π × r² ) / 2 }

C. Circumference of Circle

The total Circumference of the Circle is equivalent to twice of the radius multiplied with the π value as mentioned below –

Circumference of Circle, C = 2 × π × r

Methods To Find Circumference

Method 1 – It is not possible for us to normally or physically do the measurement of the length of the circle by making use of the scaler or ruler. Although, the same thing can be easily and conveniently applied to the polygons like squares, rectangles, and similar kinds. You can do the measurement of the circumference by using the traditional methods i.e., using the thread. The thread could be easily used for tracing the path on the circle and eventually by making the imprints on the thread. We can do so by using a normal ruler.

Method 2 – The best way to calculate the circumference of a circle is by doing the proper calculation on it. To do that, you must be aware of the radius of the circle. The radius value for the particular circle as the total distance taken from any point on the circle till the central point of the same circle. Also, the value of the diameter is equivalent to twice the radius value.
