1 answer:

6 0

A = π r^2
A = 9^2 <span>π
</span>A = 81<span>π

if using </span>π = 3.14 then

A = 3.14 x 81 = 254.47 ft^2

answer: 81π ft^2 or 254.47 ft^2

hope that helps

alternate interior angles theorem: If a transversal intersects two parallel lines, then the alternate interior angles are congruent. thus, if the alternate interior angles are congruent, then the lines are parallel.

all the angles are congruent, so m || n and p || q.

What is true about the image ΔQ'R'S'? Select three options.

sergij07 [2.7K]

Answer:

$D_{O,2} (x,y) = (2x, 2y)$

Side Q'S' lies on a line with a slope of -1.

The distance from Q' to the origin is twice the distance from Q to the origin.

Step-by-step explanation:

The explanations are as follows

As we can see from the attached figure that the ΔQ'R'S' is dilated i.e transformation is made or change in size

Now

Based on

(x,y) = (2x,2y)

The intercepts are as follows

For S

(-1,1) = (-2,2)

For Q

(-3,3) = (-6,6)

For S

(2,4) = (4,8)

Based on this we can say that the three above options are correct
