Definition of surface area:
\If the curve is described as ,
then the surface area of the curve obtained by rotating about the
-axis is
The curve is .
Differentiate on each side.
\ Area of the surface obtained by rotating the curve about the
-axis is
Step 2:
\Simpsons Rule:
\Let be continuous on
. The Midpoint Rule for approximating
is given by
,
where and
Using Simpson Rule, .
Step 3:
\Area of the surface obtained by rotating the curve about the -axis is
Using calculator, the value of the integral is .
Solution:
\Area of the surface obtained by rotating the curve about the -axis is
.
