OAB is a sector of a circle <br>what is the area of the sector
oee [108]

Answer:

12.56 square cm

Step-by-step explanation:

Central \:angle \:(\theta) = 40°\\Radius \: (r) = 6 cm

Let A be the area of the sector of circle.

\therefore \: A =  \frac{\theta }{360 \degree}  \times \pi {r}^{2}  \\  \\=  \frac{ 40 \degree}{360 \degree}  \times 3.14\times {6}^{2}  \\  \\    =   \frac{ 1}{9}  \times 3.14 \times  36 \\  \\  =   3.14 \times 4 \\ \\ = 12.56 \:  {cm}^{2}

Please help! Find the equation of the line and I will mark as brainliest IF answer is right. &lt;3
Hoochie [10]
<h3>Answer:  y = (3/4)x + 13/4</h3>

This is the same as writing y = 0.75x + 3.25

slope is 3/4 = 0.75

y intercept is 13/4 = 3.25

==========================================================

Explanation:

One marked point on this line is (-3,1)

Another point is at (1,4)

Let's find the slope of the line through these two points.

m = (y2-y1)/(x2-x1)

m = (4-1)/(1-(-3))

m = (4-1)/(1+3)

m = 3/4

m = 0.75

Now let's use point slope form to find the equation of the line

y - y1 = m(x - x1)

y - 1 = 0.75(x - (-3))

y - 1 = 0.75(x + 3)

y - 1 = 0.75x + 2.25

y = 0.75x + 2.25 + 1

y = 0.75x + 3.25

If you wanted, you can convert those decimal values to fraction form

  • 0.75 = 75/100 = 3/4
  • 3.25 = 325/100 = 13/4

That means the equation

y = 0.75x + 3.25

is the same as

y = (3/4)x + 13/4
