Answer:

6\sqrt2\\OR\\8.48528137

Step-by-step explanation:

The area of a sector of a circle is found by:

A = \frac{\theta*r^2}{2}

The question asks for the radius so the equation above can be repurposed

r = \sqrt\frac{2A}{\theta}

A = 3pi

angle = pi/12

\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72

\sqrt{72} = 6\sqrt2 = 8.48528137

A clock has a diameter of 16 inches. how far does the hour hand travel during 5 hours? use 3.14 for pi.
valentina_108 [34]

Distance hour hand travel in 5 hours is 20.94 inches.

<h3>What is a diameter?</h3>
  • A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
  • It is also known as the circle's longest chord.
  • Both definitions apply to the diameter of a sphere.

To find the distance hour hand travel in 5 hours:

  • Let's say the hour hand completed one full round around the clock.
  • If this was the case, it would have been 2\pi×8 inches around.
  • We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2\pi×8×( 5/12 ).
  • Distance hour hand travel is 20.94 inches.

Therefore, the distance hour hand travel in 5 hours is 20.94 inches.

In what quadrant would the ordered pair (-5, 4) be located?<br><br> I<br> II<br> III<br> IV
statuscvo [17]
Ok, so
 Quadrants are found on coordinate planes. So the first number tells you to go on the X axis. It goes this way ---------
you look on the left side side of the origin (zero) and go to -5
since the second umber will be found on the Y axis, and is positive, go up to 4.
That is how you find your point.  The qudrants are counted like this.
2 1 
3 4
The answer is Quadrant 2
Hope it helped☺

What are the next 3 numbers in this sequence? 1,1,2,4,7,13,24,44
Bogdan [553]
81,149, 274.... adding three numbers from the last would help you

like if you take 7 = 4 + 2 +1

or 13 = 7 + 4 +2

similarly 44+24+13 = 81
              81+44 +24 = 149
              149 + 81 +44 = 274

hope you get it!
