Circumference of circle=<span>2πr</span>

Where <span>r=radius</span>

<span>2r=d</span>

<span>d=diameter</span>

So,<span>2πr=πd</span>

Note,<span>π=<span>227</span></span>

In this statement,<span>c=ci</span><span>rcumference</span>

<span>→c=πd</span>

<span>→c=π<span>(30)</span></span>

<span>→c=π30=<span>227</span><span>(30)</span></span>

<span>→c=<span>6607</span>=94.28...</span>

Circumference is <span>94.28...cm<span>s</span></span>

Elenna [48]
We need to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:

$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard

As both prices per yard are the same, the answer is: <span>Yes, these fabrics have the same unit cost.</span>
