Answer:
Second option is correct
Step-by-step explanation:
Given:
Central angle = 15°
Radius of the circle = 9 in
Arc length = ?
Given formula is
Where n is the central angle of the sector.
Write the given formula for Arc length of the sector.
We know that the the circumference of the circle is 
, where r is the radius of the circle,
Now we substitute central angle value and radius value in above equation.
----------(
)
Divide the numerator and denominator by 5.
Therefore the arc length of the sector is 
Answer: 858
Step-by-step explanation:
Answer:
<h3>Therefore the sum if the series is 15.98!</h3>
The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.
8⋅1/2=4
4⋅1/2=2
2⋅1/2=1 etc ...
because the absolute value of r is less than 1 we can use the following formula.
a/1−r where a is the first term and r is the common ratio
In our problem
a=8 and r=0.5
Substitute
8/1−0.5=8/0.5=16
The sum of this infinite geometric series is 16.
Also, another formula you can use that is guaranteed to work every time, no matter what, is:
Sn=a(r^n−1/r−1)
All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:
S10=8(0.5^10−1/0.5−1)
S10=15.984375
Therefore the sum if the series is 15.98!
