The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi
mestny [16]

Answer:

The area of rug is 48.9 m^2

Step-by-step 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
