Answer:
Step-by-step explanation:
This problem can be solved by using the expression for the Volume of a solid with the washer method
where R and r are the functions f and g respectively (f for the upper bound of the region and r for the lower bound).
Before we have to compute the limits of the integral. We can do that by taking f=g, that is
there are two point of intersection (that have been calculated with a software program as Wolfram alpha, because there is no way to solve analiticaly)
x1=0.14
x2=8.21
and because the revolution is around y=-5 we have
and by replacing in the integral we have
and by evaluating in the limits we have
Hope this helps

216 in^2
Step-by-step explanation:
a= h x b /2
= 24in x 18in / 2
= 216inches^2
Hello
(n-2)*180 where n is the number if angles in a polygon
(38-2)*180
=36*180=6480
(29-2)*180=4860
1 angle -> 4860/29 = 167.58
You do the same here
(1026-2)*180=184,320
184,320/1026=179.64
They're complementary so 180-179.64=0.36°
(36-2)*180=6120
6120/36=174.85
180-175.85=5.15°
