Check the picture below.

so the figure is really just 3 rectangles and two triangles.

simply get the area of all 5, sum them up, and that's the area of the figure.

recall that area of a triangle A = ½bh.

An arc has a central angle of 1.8 radians and a radius of 20

Nutka1998 [239]

Answer:

a) Arc length (l) = 36 inches

The nearest angle in degrees θ = 103.18°

Step-by-step explanation:

Step(i):-

An arc has a central angle of 1.8 radians and a radius of 20 inches.

Given arc has a central angle of 1.8 radians and

radius of circle = 20 inches

Given arc has a central angle (θ ) = 1.8 radians

Arc length (l) = r θ

l = 20 × 1.8 radians

l = 36

The length of arc = 36 inches

we will convert radians to degree

1.8 × 180° / π = 324° / π ≅ 103.18°

The nearest angle in degrees θ = 103.18°

How to graph 14x+18y=126

Burka [1]

We need to rearrange this into $y=my+c$
Subtract 14x from both sides
$18y=-14x+126$
Divide both sides by 2
$9y=-7x+63$
Divide both sides by 9
$y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}$
Plot the point (0, 63/9)
Then pick some x values and put them into the equation to find the respective y values
Then plot those points
Finally join up those points
