**1. What are the important formulae to remember while studying Circles?**

All of the formulae used to calculate certain features of the circles are related to one another hence it is very easy to memorize the formulae while practicing questions on the same. Some of the formulae are as follows:

Circumference: C= 2πR (where R is the radius of the circle)

Diameter: D=2R

Length of an arc: central angle made by the arc/360°x (2πR)

Area of the circle: πR

^{2}Area of a sector: centra*l angle by the sector/360°x (πR

^{2})

**2. Where do we find the best resources for solving questions on Circles?**

R. D. Sharma class 10 Maths stands out as the best textbook with excellent questions in the form of exercises after the chapter is completed. As suggested by experts, the examples have been explained in simple words so that students can understand why and how each step of the solution has been used to solve a particular question. NCERT is also another recommended textbook by CBSE. For tips and tricks, study materials from Vedantu are also available for free and can be downloaded from the official website.

**3. How do we study the formulae of Circles?**

Formulae of the circles mostly revolve around the radius, diameter and circumference of the circles. The most important aspects of the chapter are the area of the circle and the sector. Since the formulae are not very difficult to remember, easy derivation of each formula and understanding of the concepts of the chapter are more than enough for retaining the formulae in mind ahead of the exam. If needed, short notes can be made on the modules of the chapter which could help in strengthening the grasp over the topics.

**4. How many exercises are there in R. D. Sharma class 10 Maths book?**

Circles has been added as the 10th chapter in R. D. Sharma class 10 Maths book. This chapter consists of two exercises which include area of the arc and sector, angles in the circle, properties of a tangent in a circle, lengths and distance of tangent from a point on the circle, cyclic quadrilateral and other types of tangents as well as concentric circles. Each of these questions are worded in different ways for students to analyze and find the right solutions.

**5. Are the exercises after completion of chapter enough to score well in class 10 Maths Board Exam?**

Rome wasn't built in a day and hence it takes lots of time , patience and efforts to create something monumental and worth remembering. The same can be applied for Maths in which good scores can be only achieved through regular practice. It is mandatory for students to solve examples, exercise after every chapter, Previous Years’ question papers and sample/mock papers to get a fair idea of the type of questions that might come in the exam. Special importance has to be given to formulae in every chapter because that is the base for solving Maths-related questions.
