Question

The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi

Answer 1

The area of rug is 48.9 m^2

Explanation:

Let's assume radius of rug is r m

we know formula for circumference as

`C=2\pi r`

we are given

C=24.8

and then we can solve for r

`24.8=2\pi r`

`r=3.947`

now, we can use area formula

`A=\pi r^2`

we can plug r

and we get

`A=\pi (3.947)^2`

`A=48.94227`

So,

The area of rug is 48.9 m^2
