Answer
Find out the what is the approximate length of the diameter, d .
To prove
Formula
\(Circumference\ of\ circle = 2\pi r\)
Where r is the radius of a circle .
As given
circumference of approximately 250π ft
Put in the formula
\(250\pi = 2\pi r\)
\(cancel\ \pi\ on\ both\ side\)
250 = 2r
\(r = \frac{250}{2}\)
r = 125 ft
As Diameter is double of the radius .
d = 2r
= 2 × 125
= 250 ft
Therefore length of the diameter be 250 ft .
