Answer:
v=23160.24
Step-by-step explanation:
v= r^2 * h * π
19.6 ^2 = 384.16 r = d/2
384.16 * 19.2 * 3.14 39.2 / 2 = 19.6
23160.24
Hope this isn't too confusing!

Answer:
6
Step-by-step explanation:
You can memorize these for the smaller shapes
for equilateral polygons:
triangle: 60
square: 90
pentagon: 108
hexagon: 120
Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.
So the measure of each angle on average would be (s-2)*180/s.
There (s-2)*180/s = 120
180(s-2) = 120s
180s-360 = 120s
60s = 360
s = 6
He is five feet below sea level. He descends 4 more time which is 5*4 = 20. So, -5 (below the sea level) -20 (for descending more) which is 25 feet below the sea level.
