Answer
A) 251 yards
Step by step explanation
Circumference of a circle = πd, where "d" is the diameter of the circle.
Given: d = 80 yards
Now plug in d = 80 in the above formula.
Circumference of the circe = 3.14 * 80 [π = 3.14]
= 251.2 yards
When we round off to the nearest whole number, we get
The circumference of the circle = 251 yards.
