Circumference / pi = Diameter, radius = diameter / 2
So>
37 / pi
= 11.777 diameter
= 5.8885 radius

If you wish to give your answer to 5 significant figures, you MUST use the value of pi to at least that many sig figs.
Thus, radius = 37/(2*3.1416) = 5.8887 - to 5 sig figs.

How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
If the circumference is 3.14 what is the diameter and the radius?
If the circumference is 3.14:Diameter = 1Radius = 0.5
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is the circumference of the circle with a 6 inches radius?
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
