Step 1:

\

The curve is $\"\"$ , $\"\"$ .

\

If the curve is rotating about $\"\"$ axis, area of the resultant surface is , $\"\"$

\

Where $\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Substitute $\"\"$ and $\"\"$ in area formula.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$ (Since $\"\"$ )

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

Solution:

\

The area of the surface is $\"\"$ Sq-units.
