Answer:
3π
Step-by-step explanation:
The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.
The radius is given ad 6. So the circumference is:
2*π*6=12π
Now, since the angle of the arc is 90°, this is 1/4 of the circle.
This means that the arc length of this section will be 1/4th of the total circumference which is:
12π/4=3π
Answer:
7x10 = 70 / 3 = 25

Answer:
AA similarity theorem
Step-by-step explanation:
You are given that two angles are congruent, so the appropriate choice is ...
AA similarity theorem
__
Triangle similarity is shown by demonstrating that all three sides are proportional, or that two angles match (meaning the third one must also match). These methods would be abbreviated SSS (3 Sides) and AA (2 Angles), respectively. Since your problem statement involves angles and similarity, the choice is clear.
Answer:
<em>550 </em><em>students are in the school.</em>
Step-by-step explanation:
The way I found my answer was by first turning<em> 74% into a decimal</em>, which is <em>0.74</em>. Then I <em>divided 407 </em>by<em> 0.74</em> and I got<em> 550</em>. Therefore, <em>550 is our answer.</em>
