Answer:
Radius of the circle is = [tex]3.50\,feet[/tex]
Step-by-step explanation:
Circumference of a circle is the measure of the length of its boundary that can be measured by:
Circumference of the circle= [tex]2\times \pi \times r[/tex]
For, [tex]Circumference=21.99\,feet[/tex]
As,
[tex]\pi =\dfrac{22}{7}=3.14[/tex]
Putting the values in the formula:
[tex]21.99=2\times 3.14\times r\\\\21.99=6.28\times r\\\\r=\dfrac{21.99}{6.28}\\\\ r=3.50\,feet[/tex]
The radius of the circle is : [tex]3.50\,feet[/tex]
