The circumfernce of a circus ring is 13 meters. Esimate the radius of the ring.
C = 2 r pi
r = C / 2 pi
r = 13 / 2 3.14
r = 13 / 6.28
r = 2.07 m

To estimate the radius of the circus ring, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius.
In this case, we are given the circumference, which is 13 meters. So, we can rearrange the formula to solve for the radius:
C = 2πr
13 = 2πr
To solve for r, divide both sides of the equation by 2π:
r = 13 / (2π)
Now, let's calculate the estimated value for the radius using π ≈ 3.14:
r ≈ 13 / (2 * 3.14)
r ≈ 13 / 6.28
r ≈ 2.07
Therefore, the estimated radius of the circus ring is approximately 2.07 meters.
