The picture in the attached figure

we know that
area of a sector=(∅/2)*r²--------> when ∅ is in radians

area of sector inner circle=(∅/2)*r²

area of sector outer circle=(∅/2)*R²-(∅/2)*r²

The ratio of the area of the sector removed from the outer circle to the area of the sector removed from the inner circle is
[(∅/2)*R²-(∅/2)*r²]/[(∅/2)*r²]-----> [R²-r²]/[r²]

therefore

the answer is
(R^2 - r^2)/r^2

What is the midpoint of the line segment with endpoints(-2,-2) and (4,6)

Ann [662]

Answer:

The midpoint of points $(-2,-2)\ and\ (4,6)$ is $(1,2)$ .

Step-by-step explanation:

Given points are $(-2,-2)\ and\ (4,6)$ . We need to find the midpoint of the line segment.

The formula of finding midpoints between the point $(x_1,y_1)\ and\ (x_2,y_2)$ is

$(\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2})\ Equation(1)$

W have points $(x_1,y_1)=(-2,-2)$ . And $(x_2,y_2)=(4,6)$

Let us plug the value in Equation (1)

$(\frac{-2+4}{2} ),(\frac{-2+6}{2})$

$(\frac{2}{2}),(\frac{4}{2})\\ \\(1,2)$

So, the midpoint of points $(-2,-2)\ and\ (4,6)$ is $(1,2)$ .

What effect will a 90 degree clockwise rotation have on the triangle

N76 [4]

A 90 degree clockwise rotation will leave the sides with the same length,
will leave the angles the same , it will only change the position of the triangle.

What are the coordinates of the point on the directed line segment from (-6,9) to

brilliants [131]

Answer:

Step-by-step explanation:

difference of x-coordinates = 4-(-6) = 10

difference of y-coordinates = -1-9 = -10

partition the differences into a ratio of 1:4

10 × 1/(1+4) = 2

-10 × 1/(1+4) = -2

(-6+2,9-2) = (-4,7)
