Answer:
Step-by-step explanation:
The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.
The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.
- d= 52 yd
Also, remember we are using 3.14 for pi.
= 3.14
Substitute these values into the formula.
Multiply.
The circumference of the circle is <u>163.28 yards.</u>
Answer
Step-by-step explanation:
Radius is always half of the diameter so, is equal to
.
The Formula for Circumference is
Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be:
Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)
So our answer is going to be

Answer:
AA similarity
Step-by-step explanation:
Your question is not well presented.
See attachment
Given
Triangles ABC and DBE
Required
Which postulate supports the similarities of ABC and DBE
At the first transformation (180 degrees rotation) both triangles maintain SSS and AAA relationships. i.e <em>Side-Side-Side</em> and <em>Angle-Angle-Angle</em>
This is so because rotations do not alter the side lengths; neither does it alter the angles.
When the second transformation (dilation) takes place, the lengths of both triangles ABC and DBE become different because dilation alters side lengths.
However, angle measurements remain unaltered.
<em>Hence, AAA similarity answers the question</em>
