The fixed distance is called the radius of the circle

So radius if defined as the distance between centre and any point on the circle

GENERAL EQUATION OF A CIRCLE

The general equation of a circle is

$\sf{ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \: \: }$

where (h, k) is the centre of the circle and r is the radius of the circle

EVALUATION

From above we can conclude that The measure of circle is based on Centre of the circle

Hence the part of the circle is important for making a wheel Radius
