Circumerence=2pir or dpi were r=radius and d=diameter
11pi=2pir
divid eobt sides by pi
11=2r
dvide 2
5.5=r

11pi=dpi
divide both sides by pi
11=d

diameter=11in
radius=5.5 in

An army base in the desert is located at the origin, O of an x-y coordinate system. A soldier at point P needs to determine his
Nutka1998 [239]

Answer/step-by-step explanation

The soldier at point P lie on a parabola because he determined his position and distances from towns A and B through measurement of the difference in timing (phase) of radio signals received from the two towns.

This analysis of the signal time difference gives the difference in distance of the soldier at P, from the towns.

This process is known as hyperbolic navigation.

These distances of point P from towns A and B is estimated by the soldier at point P, by measuring the delay localizes the receiver to a hyperbolic line on a chart.

Two hyperbolic lines will be drawn by taking timing measurements from the

towns A and B .

Point P will be at the intersection of the lines.

These distances of point P(The soldier's positions) from town A and town B were determined using the timing of the signals received from the two towns, due to the fact that point P was on a certain hyperbola.

Which measure is equivalent to 25,200 seconds?<br><br> 1 min = 60 s<br><br> 1 h = 60 min
sertanlavr [38]

Solution:

<u>Note that:</u>

  • 1 min = 60 sec
  • 1 h = 60 min.

<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>

  • => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes

<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>

  • => 420 minutes = 420 ÷ 60 hours = 7 hours

<u>We can conclude that:</u>

  • 25,200 seconds = 420 minutes = 7 hours
