197/pi(3.1416)=62.70(diameter)
Radius=62.70/2
R=31.35
Area=3.1416x(31.35)^2
Area=3087.63
Answer:
A
Step-by-step explanation:
You're right:) distribute the 3 and have the y alone and it's A
The information is enough because: C. because one pair of congruent corresponding angles is sufficient to determine similar triangles.
<h3>What are Similar Triangles?</h3>
Similar triangles can be formed during dilation. All corresponding angles of similar triangles are usually congruent to each other.
From the image given, the using rotation about point N and then dilation by a scale factor will make both triangles similar. Thus, with the given information, we can determine both triangles are similar because: C. because one pair of congruent corresponding angles is sufficient to determine similar triangles.

Pattern?
the pattern is
diameter= 2 times radius
diameter times 1/2=radius
area=pi times radius²
circumference=pi times diameter
circumference=2 times pi times radius
pi≈3.14
Where are the choices ? ? There are 30 marbles in the bag, and 3 of them are black. So the probability of getting a black with a random draw is 3/30 = 10% .
