Answer:
C = 50.24
Step-by-step explanation:
First, you multiply 8 by 2, to get the diameter of of 16
Then all you do is, multiply by 3.14(π) and the circumference is 50.24
Hope this helps! :)

<em>28.26 ft^2, 18.84 ft</em>
Step-by-step explanation:
We are given a circle with a radius of 3 feet;
![Area of Circle = \pi * ( r^2 ) = \pi * ( 3^2 ) = 9\pi \\](https://tex.z-dn.net/?f=Area%20of%20Circle%20%3D%20%5Cpi%20%2A%20%28%20r%5E2%20%29%20%3D%20%5Cpi%20%2A%20%28%203%5E2%20%29%20%3D%209%5Cpi%20%5C%5C)

Answer:
- ∠W = 130
- ∠X = 140
- ∠Y = 50
- ∠Z = 40
Step-by-step explanation:
Using 'y' and 'z' to represent angles with the corresponding names, we have ...
y + z = 90
(3b -1) +(2b +6) = 90 . . . . substitute the given expressions
5b +5 = 90 . . . . . . . . . . . . simplify
b +1 = 18 . . . . . . . . . divide by 5
b = 17 . . . . . . . . subtract 1
Then the angles are ...
y = 3b -1 = 3(17) -1 = 51 -1 = 50
z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be
Angles W and Y form a linear pair, so are supplementary:
W = 180 -Y = 180 -50 = 130
Angles X and Z form a linear pair, so are supplementary:
X = 180 -Z = 180 -40 = 140
Then the angle measures are ...
- ∠W = 130
- ∠X = 140
- ∠Y = 50
- ∠Z = 40
