Length of an arc = θ/2π * 2πr = rθ; where θ is the angle substended by the arc at the center.
3r = rθ
θ = 3 radians.

Answer: B. 3radians


Step-by-step explanation:

Given: Radius of a circle = r

Length of a arc = 3r

To find the measurement of the angle that subtends the arc (\theta)

We know that the length of the arc (l)=\theta\times\ r

\Rightarrow\theta=\frac{l}{r}\\\\\Rightarrow\theta=\frac{3r}{r}\\\\\Rightarrow\ \theta=3\ radians

Hence, the measurement of the angle that subtends the arc = 3 radians.

The value of n is 12. and m is 6root5

We have given the diagram,

The measurement of m,

n = 12

According to the altitude theorem

<h3>What is the altitude theorem?</h3>

The right triangle altitude theorem or geometric mean theorem is a result in elementary geometry that describes a relation between the altitude on the hypotenuse in a right triangle and the two-line segments it creates on the hypotenuse.

24/n = n/6

The Cross multiply

24 * 6 = n²

144 = n²

n² = 144

n = √144

n = 12

m^2=6^2+n^2

m^2=6^2+12^2\\m^2=36+144\\m^2=180

m=\sqrt{180} \\m=2\cdot \:3\sqrt{5}\\m=6\sqrt{5}

Hence the value of n is 12.

Order the numbers from greatest to least based on their absolute value:
Valentin [98]
<h3>Answer: |-34|, |-25|, |0.5|, |0.35|</h3>

==============================================================

Explanation:

The absolute value of a negative number is the positive version of that number

|-25| = 25

|-34| = 34

The absolute value of a positive number is that exact same number

|0.5| = 0.5

|0.35| = 0.35

Absolute value represents the distance a number is from 0 on the number line. The distance is never negative, which is why |-25| = 25 for instance.

---------------

After simplifying each absolute value, we get this list {25, 0.5, 34, 0.35}

That sorts from greatest to least to get {34, 25, 0.5, 0.35}

This means the answer is |-34|, |-25|, |0.5|, |0.35|

----------------

note: it might help to think of 0.5 as 0.50, so you can see that 0.50 is larger than 0.35
