A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)

Answer: 3x
Explanation:
x + 9 = 4x - 4 • 2
x + 9 = 4x - 8
9 = 3x - 8 (subtract x from both side)
0 = 3x - 17 (subtract -9 from both side)
And the form ax is 3x
Answer:
11
Step-by-step explanation:
first you start off by counting how many sides are on a hexagon. then you put 1 on each side. then you count by sixes tell you get exactly 65 or more. do not do 10 because you leave three people unseated.
