Answer:-Thus radius of circle O=18 cm

Explanation:-

Circumference is the distance around the circle.

Circumference of circle
$=2\pi\ r$ , wherer is the radius of the circle.

Given: Circumference of circle O
$=36\pi\ cm$

$\\\Rightarrow2\pi\ r=36\pi\\\Rightarrow\ r=18\ cm...........[\text{dividing }2\pi\text{ on both sides}]$

Thus radius of circle O=18 cm
