Answer:
10
Step-by-step explanation:
10+10= 20
20/2 = 10
C = 2 pi r
16 = 2 pi r
16/2 = pi r
8 = pi r
8/pi = r
2.55 = r
Would it be 18? Maybe not im not sure
Answer:
The answer is option C
Step-by-step explanation:
To find the length of AB we use sine
sin∅ = opposite / hypotenuse
From the question
The hypotenuse is AB
The opposite is AC
So we have
sin 54 = AC/AB
sin 54 = 16 / AB
AB = 16/sin 54
AB = 19.777
<h3>AB = 19.78</h3>
Hope this helps you
