The length of the red segment is called the diameter of the circle (D).

While the yellow ribbon represents the circumference of the circle(C).

Therefore, the formula for the circumference of a circle is,

$C=\pi D$

From the formula for the circumference of a circle above, we can see that the yellow ribbon is about pi(π) times longer than the red segment.

Given that,

$\pi\approx3.14$

Hence,

Therefore, the yellow ribbon is about 3.14 times or more longer than the red segment.
