the line $y=3$

Step-by-Step Solution

Answer

Since there is a gap between the line $y=3$ and the curve the resulting solid from revolving around the $y=3$  is shell .

Step 1. Given information

We have been given 

to find the revolved region about  line $y=3$

Step 2. Finding the revolved region

Since there is a gap between the line $y=3$ and the curve the resulting solid from revolving around the line $y=3$  is shell .
