Answer:
.
Step-by-step explanation:
I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = 
. The shaded region in blue is the region we are going to rotate.
Now, to find the volume v= 
where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= 
. Then,
v = 
= 
= 
= 
= 
= .
Those are exponents and placements of the numbers in decimal like tenths hundretdths thousandths.
