A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle. The python is 2.6π meters long. What is the radius "r" of the circle that the python forms?

The python is 2.6pi meters long. This is the circumference because it's the distance around the circle. So, C = 2.6pi

We will plug this into the formula below and isolate r

C = 2*pi*r

2.6pi = 2*pi*r

2.6 = 2*r ... divide both sides by pi

2.6/2 = 2r/2

1.3 = r

r = 1.3

Since r = 1.3, this means that the radius is 1.3 meters.
