What is the radius of 81π square inches​
MrRa [10]
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:

FC=25.9

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

13x-16=4x+11

Solving

9x=27

x=3

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

13x-16=23

Or

4x+11=23

Thus

FD^2=12^2+23^2=673

Solving

FD=\sqrt{673}

\boxed{FC=25.9}

Given a pre-image and an image, explain how you could use transformation to show they are congruent?
JulsSmile [24]
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.
