Well Diufhdk, the diameter of the circle is 3.2m so the radius= 3.2/2=1.6m
which means the circumference of circle= 2*pie*r= 2*3.14*1.6=10m

Equanimity
The circumference formula for a circle is 2PiR, or 2 x Pi (3.14) x the radius, or PiD (Pi x Diameter).
Multiply 3.14 by 3.2 for our circumference.
3.14 x 3.2 = 10.048.
Your Circumference is 10.048 (if not rounded). If rounded, 10.05.
I hope this helps!
