Answer:
The radius of the circle is 18 cm.
Step-by-step explanation:
The circumference of circle O is 36π cm.
The formula for circumference of circle is
[tex]C=2\pi r[/tex]
Where, r is the radius of the circle.
Put C=36π, to find the radius of the circle.
[tex]36\pi=2\pi r[/tex]
Divide both sides by 2π.
[tex]\frac{36\pi}{2\pi}=r[/tex]
[tex]18=r[/tex]
Therefore the radius of the circle is 18 cm.
