Answer:
2.29 rads
Step-by-step explanation:
The length of the arc of a circle of radius r is given by;
l = rθ ---------------------------(i)
Where;
l = length of the arc
θ = central angle o that intercepts that arc and measured in radians.
From the question:
l = 16ft
r = 7ft
Substitute these values into equation (i) as follows;
16 = 7θ
Make θ subject of the formula
θ = 
θ = 2.29
Therefore, the radian measure of the central angle is 2.29 rads
Answer: B, C, D
Step-by-step explanation:
since it is rotated, the parallel sides stay parallel.
Side makes 846 because side = area to the power of 2
Answer:
The slope would be: -2
Step-by-step explanation:
To find the slope of these two points:
(0,4) and (3,-2)
You would have to use the formula of slope to find it.
The slope formula is:
<h2><u>y₂ - y₁ </u></h2><h2>X₂ - X₁ </h2>
So subsitute in Those two points
(0,4) would be your (x₁ , y₁)
(3,-2) would be your (x₂ , y₂)
So your formula witht he subsituted #'s in it would look like:
<h2><u>-2 - 4</u></h2><h2>3 - 2</h2>
Your answer would be:
<h2><u>-6</u></h2><h2> 3</h2>
Simplified, it is -2
<h3>So your slope is -2</h3>
<u />
The formula to use is F +V -E = 2
F = Faces = 16
V = Vertices = 14
E = edges = Unknown
We can fill in the information we have and solve for edges:
16 + 14 - E = 2
Add 16 and 14:
30 - E = 2
E = 30-2
E = 28
There are 28 edges
