Answer:

182 km

Step-by-step explanation:

They travel 39 km in 18 minutes we want to figure out how much kilometers they travel in 1 minute. What you can do is 39 km / 18 minutes and that gives you 2.16667 km in 1 minute but you want to figure out how much it is for 1 hour and 24 minutes. To do this we need to figure out how many minutes there are in 1 hour and 24 mins, but with prior knowledge we know 1 hour has 60 minutes and 60+24 is 84. We then do 84 times 2.16667 and that gives you 182 km in 1 hour and 24 minutes.

What's the approximate area of a segment of a circle with a height 6 m and the length of the chord is 20 m
storchak [24]
Given:
height = 6m
chord = 20 m

We need to find the radius of the circle.

20 m = 2 √ [ 6m( 2 x radius - 6 m ) ] 
20 m / 2 = 2 √<span>[ 6m( 2 x radius - 6 m ) ] / 2 </span>
10 m = √<span> [ 6m( 2 x radius - 6 m ) ] </span>
(10 m)² = √[ 6m( 2 x radius - 6 m ) ] ² 
100 m²<span> = 6 m( 2 x radius - 6 m ) </span>
100 m²<span> = 12 m x radius - 36 sq m </span>
100 m² + 36 m² = 12 m x radius - 36 m² + 36 m² 
136 m²<span> = 12 m x radius </span>
136 m²<span> / 12 m = 12 m x radius / 12 m </span>
<span>11.333 m = radius 
</span>
the area beneath an arc: 

<span>Area = r</span>²<span> x arc cosine [ ( r - h ) / r ] - ( r - h ) x </span>√<span>( 2 x r x h - h</span>²<span> ).
</span>
<span>r</span>²<span> = (11.333 m)</span>²<span> = 128.444 m</span>²<span> </span>
<span>r - h= 11.333 m - 6 m = 5.333 m </span>
<span>r * h = 11.333 m x 6 m = 68 m</span>²

<span>Area = 128.444 m</span>²<span> x arc cosine [ 5.333 m / 11.333 m ] - 5.333 m x </span>√<span>[ 2 x 68 m</span>²<span> - 36 m</span>²<span> ] </span>

<span>Area = 128.444 m</span>²<span> x arc cosine [ 0.4706 ] - 5.333 m x </span>√<span> [ 100m</span>²<span> ] </span>

<span>Area = 128.444 m</span>²<span> x 1.0808 radians - 5.333 m x 10 m </span>

<span>Area = 138.828 m</span>²<span> - 53.333 m</span>²<span> </span>

<span>Area = 85.4 m</span>²
