The length of an arc in a circle is radius x the angle (Ф).
Mind you angle Ф should be in radian.
1st let's convert 40° into radian
40/180 = x/π===> x=(π x 40)/180 ==> x = 2π/9 = 0.698 radian
so the arc length = 0.698 x 8 =5.585
The length of each arch segment is 6ft.
<h3>What is a quadratic equation?</h3>
Quadratic equation is an algebraic equation with the highest power of its variable as 2.
Analysis:
The points at which the curve touches the floor, f(x) = 0
so, - +2x + 8 = 0
- +4x -2x +8 = 0
-x(x-4) -2(x-4) = 0
(-x-2)(x-4) = 0
x = -2 or 4
so length of segment along the floor of each arm, the distance from -2 to 4 on a graph is 6 = 4--2 = 6 feet
In conclusion, the length of the segment along the floor of each arch is 6 feet
