The approximate length of rail that needs to be replaced is 7.1 ft
<h3>Length of arc</h3>
Since the pool is circular, the approximate length that needs to be replaced is an arc of length, L = Ф/360° × πD where
- Ф = central angle of rail section = 27° and
- D = diameter of circular pool = 30 ft
<h3>Approximate length of rail</h3>
So, substituting the values of the variables into the equation, we have
L = Ф/360° × πD
L = 27°/360° × π × 30 ft
L = 3/40 × π × 30 ft
L = 3/4 × π × 3 ft
L = 9/4 × π ft
L = 2.25 × π ft
L = 7.07 ft
L ≅ 7.1 ft
So, the approximate length of rail that needs to be replaced is 7.1 ft

Answer:
0.102
Step-by-step explanation:
because 0.102-0.024>0, meaning it has more. also the second number has a . tenth while the first number has 2 hundreths, which is smaller
The value of x would be 15 degrees.
This is a right angle and right angles are 90 degrees in total.
90-30= 60
We know that the missing part of the angle equals 60 degrees so we divide 60 by 4x.
60/4x=15.
I hope that was clear enough, sorry if it’s not. Have a great day and good luck!
V=LWH
V=(3)(12)(8)
V=288 m³
because
3m times 12m times 8m is
288 m³
