Question

can some one help me with this?:
A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle. The python is 2.6pi meters long.
What is the radius r of the circle that the python forms?

Answer 1

2.6pi is the circumference 
circumference is 2pi*r
so 2.6pi=2pi*r
2.6=2r
r=1.3
The radius should be 1.3 meters
