Circle O has a circumference of approxim

aev [14]

Answer:

80 ft

Step-by-step explanation:

Circumference is approximately 250 ft

We want to find the diameter.

Circumference of a circle = π × D (D is the diameter)

So πD ≈ 250 ft

D ≈ $\frac{250}{Pi}$ ≈ 79.57747155

Diameter is approximately 80 ft.
