If the diameter of a circle is 18.2cm , find its radius .
Finding the radius of the circle
The diameter of the circle = 18.2cm ( Given )
Radius of the circle = 18.22 ( since , radius is half of the diameter )
= 9.1 cm
Therefore , Radius of the circle = 9.1 cm
If diameter of a circle is 18 cm, then the radius is ____ cm.
