CAN SOMEONE PLEASE HELP ASAP!?? I RLLY NEED THIS
Sindrei [870]

Answer:

109 degrees

Step-by-step explanation:

Since we can see that the line on the top, the one across the yellow box, is the main one, and that one measures 180*, so that means that we have to just subtract 180 by 71, and that will be our answer!

180-71 =109

So, the angle of the missing angle is 109 degrees.

Another proof that this is your answer is that 109 degrees is obtuse, and we can easily say that the angle here is also obtuse.

Consider the volume of the region shown below, which shows a right circular cone with top radius 3 cm and height 10 cm. We have
koban [17]
I have the same problem here with a slight change in the given values:

radius is 2 & height of 6 indicates the bounding line is y = 3 x---> x = y / 3.... 

<span>thus the [ π radius ² thickness ] yields π (y² / 9 ) <span>dy ,</span> y in [ 0 , 6 ] for the volume... </span>

a Riemann sum is then : y_i = 0 + i [ 6 / n ] = 6 i / n , i = 1,2,3...n and do a right side sum 

<span>π Σ { i = 1,2,3..n } [ 36 i² / 9 n² ] [ 6 / n ]
</span>
I hope my guide has come to your help. God bless and have a nice day ahead!
