Answer:

Radius of the circle is =
$3.50\,feet$

Explanation:

Circumference of a circle is the measure of the length of its boundary that can be measured by:

Circumference of the circle=
$2* \pi * r$

For,
$Circumference=21.99\,feet$

As,

$\pi =(22)/(7)=3.14$

Putting the values in the formula:

$21.99=2* 3.14* r\\\\21.99=6.28* r\\\\r=(21.99)/(6.28)\\\\ r=3.50\,feet$

The radius of the circle is :
$3.50\,feet$
