Answer:
27.0 feet
Step-by-step explanation:
Length of an arc (s) = 2πrθ/360................. Equation 1
Where r = radius of the circle, θ = angle in degree substends by the arc at the center of the circle.
From the question,
Given: r = 9 feet, θ = 3 radian = 3 (57.2950) = 171.89°
Constant: π = 3.14
Substitute these values into equation 1
s = 2(3.14)(9)(171.89)/360
s = 9715.2228/360
s = 26.99 feet
s ≈ 27.0 feet
Answer: It is a 40 degree angle
The answer to this question would be
5= rotating 90° clockwise
6= mirrored diagonally (\)
In this case, the picture in number 5 is moved 1 quadrant to the clockwise direction. In this problem, it is either the picture rotated 90° clockwise or mirrored to the Y lines. If it mirrored, the effect would be X point become minus. But seeing the point B and C, the effect is
1. X and Y switched
2. X become minus
This effect is gained when you rotating 90° clockwise
In number 6, the picture moved 2 quadrants. It will be either rotated 180° or mirrored diagonally. The effect on the image is:
1. X and Y switched
2. Both X and Y become minus
This effect is gained if the shape was mirrored.
A decrease in the ratio 4:5 implies that :
New quantity:Old quantity = 4:5
Let the new quantity be 
So, the new quantity is 32
