Answer:

Step-by-step explanation:

The following ratio is true for any circle

$\frac{arc}{C}$ = $\frac{centralangle}{360}$ ← C is circumference

$\frac{4}{C}$ = $\frac{30}{360}$ ( cross- multiply )

30C = 1440 ( divide both sides by 30 )

C = 48 → A

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing

ANEK [815]

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:

$\frac{1}{6} *x$

We also know how big it is:

$\frac{1}{6} *x= \frac{1}{1 500}$

now, let's multiply both sides by 6:
$\frac{6}{6} *x= \frac{6}{1 500}$
$1 *x= \frac{3}{750}$
$x= \frac{1}{250}$

So the answer is that it would be $x= \frac{1}{250}$ miles wide
