What are the properties of Circle in ICSE class-9 mathematics?
Visit official Website CISCE for detail information about ICSE Board Class-9 Mathematics. Some of the important properties of the circle are as follows: The distance from the centre of the circle to the longest chord (diameter) is zero The perpendicular distance from the centre of the circle decreases when the length of the chord increases

What is the area of a circle?
You may also recall that area of a circle is ?r2, where r is the radius of the circle.Recall that you have verified it in Class VII, by cutting a circle into a number ofsectors and rearranging them as shown in Fig. 12.2. and breadth r. This suggests that the area of the circle = × 2?r × r = ?r2. Let us
