NCERT Solutions Class 7 Maths Chapter 11 Exercise 11.3 Perimeter and Area

The next geometrical figure covered in the NCERT solutions for class 7 maths chapter 11 exercise 11.3 Perimeter and Area is Circle. The area of the circle is the amount of space enclosed by the curved line, and the circumference of the circle is the length of the curved line as per the simple geometric principles. Their calculation involves a new value called ‘pi’ or π. The students will be required to use the area, and perimeter formulas involving ‘pi’ to solve the values asked in the NCERT solutions class 7 maths chapter 11 exercise 11.3 problems. There are 17 questions, 10 of them are relatively easy, 3 are moderately easy, and 2 a bit on a difficult level.

The students will learn that in the case of circles, their perimeter is referred to as the ‘circumference’ and how both the area and the circumference formula are based on the value of ‘pi’. The class 7 maths NCERT solutions chapter 11 exercise 11.3 Perimeter and Area questions are below:

NCERT Solutions Class 7 Maths Chapter 11 Exercise 11.3 Tips

The students should be clear with the concept of circles. The circle is the simplest basic shape, which has no vertices or corners and is made up of a single smooth curved line. This curve runs around a fixed point called the circle's center, and all the points on the circle are equidistant from it. The diameter of a circle is calculated by the distance between the circle's perimeter and its center.

Also, they must ensure to go through the explanations of how the NCERT solutions class 7 maths chapter 11 exercise 11.2 formula of a circle are interrelated, as this will help them calculate various other measures.
