Drive a peg into the ground. Form a loop at both ends of a thin rope measuring 5 meters. Slip one looped end of the thin rope over the peg. Put a stick in the other loop and stretch the rope taut. Move the stick in a circle, keeping the rope taut, scoring a line on the ground with the end of the stick.
Instead of a stick, a piece of chalk, or an aerosol can of paint could be used to mark the ground.
The circumference of a circle with a radius of 5 meters is: about 31.42 meters.

5 m (31.4 / 2 pi)
2*pi*5 (or 2*3.14*5)
The circumference of a circle with a radius of 5 meters is: about 31.42 meters.
The radius is about 5 meters (4.997m)
The radius is about 5 meters.
If the circumference of a circle is about 31.4 meters, the radius will be about 5 meters (4.997m).
r = 5

2*pi*5 (or 2*3.14*5)
2 pi R = 10 pi = 31.416 meters (rounded).
The answer will depend on the units used for the measurement of the radius: 5 WHAT? It is trivially simple to draw 12 circles, each with a radius of 5 millimetres.
