Because circumference c = Pi x diameter
(36 x Pi) circumference = diameter = 36
therefore the radius = 36/2 = 18.
or
c = 2.Pi.r so r = c / 2.Pi
therefore
36.Pi / 2.Pi = 18

The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
The answer depends on what is 36 cm: the radius, diameter or some other aspect of the circle.
It is the name given to the straight line from the centre of a circle to its circumference when that distance is 36 inches.
The radius of a circle with a circumference of 110 is: 17.507
The circumference of a circle with a radius of 6.7 is: 42.097
