Question

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?

Answer 1

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.
