Question

if the diameter [d] is a line passes therough the centre and having its end points on the circle and radius [r] is the distance of the circle and its centre then write radius[r] in the terms of its diameter [d]

Answer 1

radius ( r) = Half of diameter

Answer 2

${\huge {\mathfrak {Answer :-}}}$

We have,

Radius = r.

Diameter = d.

Since, radius = diameter / 2

So, r = d/2
