39/2=19.5
The answer is 19.5

The circumference of a circular garden is 122.46.

The formula for the circumference of circle = [tex] 2\pi r [/tex]

Where 'r' is the radius of the circle

We need to find out radius 'r'

C = [tex] 2\pi r [/tex] where the value of [tex] \pi [/tex]= 3.14

122.46 = 2 * 3.14 * r

122.46 = 6.28 * r

r = 19.5

The radius of the circle is 19.5
