Note:
The area of a circle with radius r is πr².
An entire circle has a central angle of 360°.

For the sector with radius = (3+4) = 7cm and a central angle of 120°, the area is
A_{1}= \frac{120}{360}*(49 \pi ) = \frac{49}{3} \pi \, cm^{2}

For the sector with radius =  3 cm and a central angle of 120°. the area is
A_{2}= \frac{120}{360} *(9 \pi ) = 3 \pi  \, cm^{2}

The area of the shaded sector (see the figure) is
A=A_{1}-A_{2} = ( \frac{49}{3} -3) \pi  =  \frac{40}{3} \pi  \, cm^{2}

Answer: \frac{40}{3}  \pi  \, cm^{2}

What's the slope of the line passing through the points -1, 8 - 7, 3​
tatuchka [14]

Answer:

slope = 5/6

Step-by-step explanation:

Since you were given two points, you can use the point-slope formula to find the slope. The general equation looks like this:

y₁ - y₂ = m(x₁ - x₂)

In this formula, "m" represents the slope. To find the slope, plug the values from the two points into the equation. Make sure to put the values from the same point in the variable with the same number.

Point 1: (-1, 8)

Point 2: (-7, 3)

y₁ - y₂ = m(x₁ - x₂)                          <----- Original formula

8 - y₂ = m(-1 - x₂)                           <----- Plug in "x" and "y" values from Point 1

8 - 3 = m(-1 - (-7))                           <----- Plug in "x" and "y" values from Point 2

5 = m(-1 - (-7))                                <----- Simplify left side

5 = m(6)                                        <----- Simplify inside parentheses

5/6 = m                                       <----- Divide both sides by 6

Dough says that the opposite of -2/5 is 5/-2 is he correct
Eduardwww [97]

Answer:

No he is not correct. As the answer would be -2/5 = -0.4 and 5/-2 = -2.5 as the answer is also not opposite.
