What is a circle?
A circle is simple and closed figure made up of curved line.
Does circle have straight lines?
NO, It is made up of curved line only.
Is circle a polygon?
Since polygon is made up of straight lines whereas a circle is made up of only curved lines, it’s correct to say that a circle is not a polygon.
What is the definition of a circle?
A circle is a simple closed curve in which all points on it are at the same distance from a fixed point.
Define Centre of a circle.
The fixed point mentioned in the definition of the circle is called the centre of a circle.
What is radius of a circle?
The fixed distance mentioned above in the definition of circle is called the radius.
How many radii are there in a circle?
Radii is plural of radius. When we talk about more than one radius we call it radii. There are infinitely many radii in a circle.
What is chord of a circle?
A line segment obtained by joining any two points on a crick are called chord off a circle.
What is Diameter of a circle?
A chord of a circle which passes through the centre of a circle is called the diameter of the circle.
How can we find radius when diameter is known and vice-versa?
Firstly , radius is smaller in value than diameter. Radius is half of a diameter whereas diameter is double the radius.
Radius = diameter ÷ 2
Diameter = 2 × radiusTime to Practice! Get your pencils ready, young mathematicians! We’ve got more questions for you to solve.
