Question

Round to the nearest tenth

Answer 1

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`
