-----------------
Circumference = 2(pi)r
C = 2(3.14)4.1 = 25.748

C=2%2Api%2Ar Start with the circumference of a circle formula


C=2%2Api%2A4.1 Plug in r=4.1


C=25.76106 Multiply 2, pi and 4.1 (you can use 3.14 for pi) to get 25.76106



So the circumference of a circle with a radius of 4.1 meters is 25.8 meters (rounded to the nearest tenth)
