IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
radius = diameter/2
triangles don't have radius'
The radius is 11.
