Answer 1

Circle O has a circumference of approximately 250π ft. What is the approximate length of the diameter, d? 250

Answer 2

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 = (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 .
