b = 78°

The angles at a point sum to 360°

that is 45 + 237 + b = 360

282 + b = 360 ( subtract 282 from both sides )

b = 360 - 282 = 78°

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

the perimeter of a rectangular field is 346 yards if the length of the field is 92 yards what is its width

Maslowich

the formula for the perimeter of a rectangle is

P= 2(L+W)

with L representing length and W representing width

since we have the perimeter and the length, we can plug the values into the equation to find W

346 = 2(92+w)

346 = 184 + 2W

162 = 2W

81 = W

the width of the field is 81 yards.

hope this helped!
