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 2.6 pie meters long. What is the radius r of the circle that the python forms?

Answer 1

The answer is 1.3

Explanation:

Because it is half of the diameter which was 2.6

Answer 2

r = 1.3 meters

Explanation:

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.

The python is 2.6 pi (2.6π) meters long.

What is the radius r of the circle that the python forms?

Now we have: C = π d, or (with d = 2 r): C = 2 π r.

Changing that around: r = C / 2 π

So with our value of C = 2.6π meters, that gives us:

r = 2.6π/2π = 2.6/2, so r = 1.3 meters
