See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius

and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given

, i.e.

.
The volume is then
Whole numbers start from 0 so i am guessing that you can find the decimal for 5/6=0.833 and then multiply .
Answer:
Step-by-step explanation:
The zeros are the values of x for which y=0.
The zero of this graph is x=1.
4x - 4y = -36
3x + 4y = 8
7x = -28
/7 /7
x = -4
-4 - y = -9
+4 +4
-y = -5
/-1 /-1
y = 5
(-4 , 5)
There you go hope that’s helps !!!
