Apothem = 6.364
radius^2 = 6.364^2 + 6.364^2
<span><span><span>radius^2 = 81</span></span></span>
radius = 9
Formula to find the central angle is,

Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and
.
First step is to plug in these values in the above formula. So,

By simplifying.
Since 

s=14.65
Hence, arc length iss 14.65 feet.

Answer:
22
Step-by-step explanation:
21.6 would round up because 6 is closer to 10 than it is 0
Answer and Step-by-step explanation:
The area formula for a Circle is:
A = 
Diameter is equal to the radius times 2.
<u>So, divide the diameter to get the radius.</u>
6 divided by 2 equals 3.
<u>Now, plug it into the formula.</u>

A = 
Plug this into your calculator by multiplying 9 by pi.
<u>We get the answer to be 28.3 when rounded to the nearest tenth.</u>
