Surface Area of revolution

Hi

how would I calculate the surface area of revolution for this curve (using an accuracy of 10^-5) if i rotate it about the axis.

from the graph, it can be seen on the y-axis that the interval of integrating would be from 0 to 40 so it would be easy to rotate about the y axis I would think.

Hello Rumaanah,

take a look at the theorem of Pappus, It's a great part of our cultural heritage to be able to consult a Greek guy from the 4th century

The following link has an answer to calculate volume under surface of revolution of a curve. This may also be extended to calculate the surface area as well.
