Dan is using a compass to navigate back to base camp the compass has a diameter of 4 centimeters what is the compass radius

The compass radius is 2 centimeters.

The radius of a circle is equal to half of its diameter.

Given that the diameter of the compass is 4 centimeters, the radius can be calculated by dividing the diameter by 2:

Radius = Diameter / 2
Radius = 4 cm / 2
Radius = 2 cm

Therefore, the radius of the compass is 2 centimeters.
