Option C:
Perimeter of the 
of a circle = 10.71 cm
Solution:
Given figure is of a circle.
It is a quarter of a circle.
Radius = 3 cm, Value of <em>π</em> = 3.14
To find the perimeter of the quarter of a circle.
Perimeter of the quarter of a circle formula: 
Perimeter of the quarter of a circle = 10.71 cm
Option C: 10.7 is the correct answer.
Hence perimeter of the of a circle is 10.71 cm.
Answer:
2 in 52.3
Step-by-step explanation:
the two in 52.3 represents 2
<h3>Answer:</h3>
Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis
<h3>Explanation:</h3>
The problem statement tells you the transformation is ...
... (x, y) → (x, -y)
Consider the two points (0, 1) and (0, -1). These points are chosen for your consideration because their y-coordinates have opposite signs—just like the points of the transformation above. They are equidistant from the x-axis, one above, and one below. Each is a <em>reflection</em> of the other across the x-axis.
Along with translation and rotation, <em>reflection</em> is a transformation that <em>does not change any distance or angle measures</em>. (That is why these transformations are all called "rigid" transformations: the size and shape of the transformed object do not change.)
An object that has the same length and angle measures before and after transformation <em>is congruent</em> to its transformed self.
So, ... ∆P'Q'R' is a reflection of ∆PQR over the x-axis, and is congruent to ∆PQR.
701 = 21 + 68w
701-21= 680
680/68=10
w=10
The given expression is a perfect square trinomial.
<h3>
How to classify the given expression?</h3>
Here we have the expression:
Notice that we can rewrite it as:
Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:
We will have:
Which is in fact, a perfect square trinomial.
