ehhh- i give up
Step-by-step explanation:
I agreed Angle 4 and 12 is the right answer
Find the area of the surface generated by revolving x equals t plus StartRoot 2 EndRoot , y equals StartFraction t squared Over 2 EndFraction plus StartRoot 2 EndRoot t plus 3 , negative StartRoot 2 EndRoot less than or equals t less than or equals StartRoot 2 EndRoot about the y dash axis. The surface area obtained by revolving the given curve around the y dash axis is
???
Answer:

Step-by-step explanation:
The given parametric equations are;


We make t the subject in the second equation to get:

We substitute into the first equation to get:

We use the relation:
and
