Question

A circular rug has a circumference of exactly 30.14 feet which measurement is closest to the radius in feet of the rug.

Answer 1

`r=4.8\ ft`

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

solve for r

`r=(C)/(2\pi )`

we have

`C=30.14\ ft`

substitute

`r=(30.14)/(2\pi)=4.8\ ft`
