Question

Find the radius of the circle if the diameter is:

$12cm$

Answer 1

Diameter of the circle is twice the radius of the circle.

$d=2r$

$r=\frac{d}{2}$

Given diameter of the circle $=12cm$

Radius of the circle $=\frac{12}{2}cm=6cm$

Hence, Radius of the circle is $6cm$ if the diameter is $12cm$
