Answer:
B
Step-by-step explanation:
My power of guesssing :)
D
Translations, Reflections, and Rotations are transformations that result in a congruent figure.
Dilations on the other hand don't. They change the size of the figure, which means the transformed figure is not congruent to the original.
Okay, first, given the equation, we need to find out what the radius of the circle is. Let us state the general equation of a circle:

Where

is the centre of the circle. In this case, we don't need to know the centre. Just the radius.
Let us start by converting the equation into standard for, which I typed above. Divide both sides by 81.

Great! We now know the radius of the circle. It is

because it is the bottom fraction. Now we know that the radius is 9.
So now lets input this into the area of circle formula:
Now we insert our radius.
You can convert that into a decimal if you wish.
Hope this helped!

Answer:
y = x
Step-by-step explanation:
The inverse of f(x) = x is just y = x.
285 inches = 7.91667 yards
so if you round up they are equal but if you don't they are not equal
