Answer:
See answer below
Explanation:
Hi there,
Please recall the circumference formula:
where
= 3.14159... the irrational constant and r is the radius of the circle.
The dotted line across the circle cuts through its center, from one end point to the other, the definition of the diameter...
Since the diameter is related to radius, we can calculate the circumference as follows:
![C = 2\pi ((d)/(2))^ = 2(\pi d )/(2) = \pi *d = \pi * (13 \ yd) = 40.84 yd](https://img.qammunity.org/2021/formulas/mathematics/college/fpe4aum0zq51vb73z80wci8yaqcduzz9dd.png)
Hence we obtain a circumference length of 40.84 yards. Study well and persevere.
thanks,
