The relation between time, speed, and distance is ...
time = distance/speed
time = (15 km)/(0.5 km/h) = 30 h
It takes 30 hours for the lava to reach the sea.
V = pi r^2 * h
V = pi * 9 * 6
V = 54 pi in^3

<em>x = 25°</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>We know : </em><em><u> the sum of the measures of any triangle is 180 degrees</u></em><em>.</em>
<em>A + B + C = 180°</em>
<em>(3x - 13) + (2x + 4) + (180 - 116) = 180</em>
<em>5x - 13 + 4 + 64 = 180</em>
<em>5x = 180 - 64 - 4 + 13</em>
<em>5x = 125</em>
<em>x = 125 : 5</em>
<em>x = 25°</em>
<em>Good luck !</em>
