Answer: 1 to 8
Reason: because there’s 1 of 8 items is the same ratio
It is 9 inches because the formula for the area of a circle is πr2 where the r represents the radius of the circle
The pi can be canceled out =
πr2 and 81 π leaving with
R2 and 81
The r2 represents a square number. So square root 81 and you would result in 9 as your answer
Answer:

Step-by-step explanation:
<u>Congruent Triangles</u>
The figure shows two triangles FCD and FED. One of their sides is the radius of the circle, they both form a 90° angle with the line CD and ED and they share the same segment FD.
Thus, both triangles are congruent and we have the length of a side (12 units), one common side (the hypotenuse) and one unknown leg that must be equal. Therefore

Solving


The required side FD is the hypotenuse of any of the triangles. The unknown leg can be calculated by

Or

Thus

Solving


You would need to know how long the path is to answer this question
Given a pre-image, you could use any single reflection, rotation, or translation, or combination of these transformations to re-position the pre-image on top of the image to confirm congruence. You would be able to visually see corresponding side lengths and corresponding angles measures are the same.
