We, at cbseinsights.com have come up with the CLASS-10 MATHS FORMULAE AREA-RELATED-TO-CIRCLE for the easy grasping of the concepts by the Student. Besides, The Formulae will help the students to have easy grasping of the concepts in the CBSE Boards and various Competitive Exams.

• The distance around the circle or the length of a circle is called its circumference or perimeter.
• Circumference (perimeter) of a circle = πd or 2πr,
where d is a diameter and r is a radius of the circle and π = 22/7
• 1. Area of a circle = πr2
• 2. Area of a semicircle = 1/2 πr2
• 3. Area of quadrant = 1/4 πr2
