What is the radius of this circle if the circumference is 18π cm? <br> 3 cm 9 cm 18 cm 36 cm
AveGali [126]

Answer:

The radius is 9 cm.

Step-by-step explanation:

The formula for calculating the circumference of a circle is

C=2\pi r

Where r is the radius and C is the circumference.

It was given in the question that; the circumference, C=18\pi cm.

We substitute this into the formula to obtain;

18\pi=2\pi r

Divide both sides by 2\pi

\frac{18\pi}{2\pi}=r

9=r

The radius is 9cm
