Answer:
C.
Step-by-step explanation:
<D and <A are vertical angles.
Vertical angles are congruent.
Congruent means the same or equal.
4.0
.40
.040
Sorry if im wrong but im sure the second one is correct
The circumference of a circle is pi x diameter. Therefore, we can use this in reverse order as well.
I’ll be using 3.14 as pi, but if you need a more exact answer you can always use the pi function on a calculator.
37.68/3.14 = 12
Therefore, the diameter must be 12.
Since the radius is half the diameter, we can divide by 2 to find the radius.
12/2 = 6
Therefore, the radius of our circle is 6.
The area of a circle is equal to pi x radius squared.
Since we know our radius, we can solve.
Using PEMDAS, we know to use exponents first, so 6 squared is equal to 36.
From there, we can multiply.
36 x 3.14 = 113.04
And there we have your answer! 113.04 is the area of the circle.
Hope this helped :)
A 270° counterclockwise rotation leads to this transformation:
(x,y) → (y, - x)
So, we have
original point new point
J (-6,2) → J' (2,6)
K (-4,6) → K' (6,4)
L (-3,3) → L' (3,3)
M (-5,-1) → M' (-1,5)
So, you have the points J', K', L', and M' that define the new parallelogram.
Answer: The coordinates of the endpoints of the side congruent to side KL are the coordinates of K' and L' which are (6,4) and (3,3).
