# The diameter of a circle is a line which joins two points on the circle and also passes through the centre of the circle. (In the adjoining figure (Fig 11.12) AB is a diameter of the circle; C is its centre.) Express the diameter of the circle (d) in terms of its radius (r).

**Solution:**

We know that diameter is twice the length of the radius of the circle.

Given that C is the centre of a circle, CP is the radius denoted by r and AB is a diameter denoted by d

So, Diameter = 2 × Radius

= 2 × r

= 2r

Therefore, 2r is the diameter of the circle in terms of its radius.
