Respuesta :

The radius of the circle is 2.86 cm.

Step-by-step explanation:

Given,

The circumference of the circle = 18 cm

To find the radius of the circle.

Formula

The circumference of a circle of radius r is 2πr

According to the problem,

2πr = 18

or, r = [tex]\frac{18X7}{22X2}[/tex] = 2.86 (approx)

Hence,

The radius of the circle is 2.86 cm.
