The diameter of a circle is a line segments which joins two points on the circle and also passes through the centre of the circle. (In the adjoining figure AB is a diameter of the circle; C is its centre.) Express the diameter of the circle (d) in terms of its radius (r).

Question

Philoid · Accepted Answer

Here,

In the given question,

We know that,

CP is the radius r of the circle

And,

AB is the diameter of the circle,

And,

C is the centre of the circle

We can also see that,

AB = 2CP

Hence,

We can say that,

The diameter of the circle is two times the radius of the circle.
