ZanzabumX [31]

Answer:

4(x^2 +10 +21)

4(x+3)(x+7) = 0

Smaller

4(x+7) = 0

4x +28 = 0

4x = -28

x = -28/4

x = -7

Larger

4(x+3) = 0

4x + 12 = 0

4x =-12

x = -12 / 4

x = -3

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
