Answer 1

80 ft

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 ≈
`(250)/(Pi)` ≈ 79.57747155

Diameter is approximately 80 ft.

Answer 2

The approximate length of the diameter, d is 250 ft

What is the length of the diameter?

The diameter is the length of the line that meets two points on the circle's periphery and passes through its center.

Circumference of circle 'C can be expressed as

`C = 2\pi r`

r= radius

`250\pi = 2\pi r`

`r = (250\pi )/(2\pi )`

r= 125

diameter = 2r

= 2×125

= 250ft
