Which list shows these lengths in order from greatest to least?
finlep [7]

9514 1404 393

Answer:

  √3/11, π/24, 3/25, 9/100

Step-by-step explanation:

The 2-decimal value of each of the numbers is ...

  9/100 = 0.09

  π/24 = 0.13

  3/25 = 0.12

  √3/11 = 0.16

Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...

  √3/11, π/24, 3/25, 9/100 . . . . . matches choice B

I need someone to explain this for me
Novay_Z [31]

Answer:

x = 6

Step-by-step explanation:

Basically 16x + 14 = 180 - 70 because equal angles are subtended by the transversal for two parallel lines.

So, 16x = 96 and x = 6.

For the given central angle, determine the distance traveled along the unit circle from the point (1, 0). 360 degrees a. 6.28 un
Alekssandra [29.7K]

Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
