This means the surface area of a single face is $\frac{100}{3}$, So we multiply by six to get the total surface area: $\frac{600}{3} = 200$ And going the short way gives us $2(10)^2 = 200$. Both ways give us the same solution.
Suppose the ellipse has equation $\frac{x^2}{b^2}+\frac{y^2}{a^2}=1$. I understand the way to obtain the surface area of the ellipsoid is to rotate the curve around y-axis and use surface of revolution.
The problem is that I have no real idea about how to find the surface area. I have learned formulas for circles, and I know the equation for an ellipse; however, I don't know how to apply that. The only idea I can think of is to put an egg on a sheet of paper and trace it, and then measure the outline drawn, and then try to find an equation for ...
The Surface Area of a Cone is $$= \pi RS$$ where S is Slant Height of the Cone. If we try to argue on this explanation of Surface Area then our explanation for Volume is in contradiction. Share
$\dagger$ this is the same as the area of the $2R\times t$ face of the wedge which leads to a simple proof that the surface area of a sphere is the same as that of its surrounding cylinder Share Cite
I know the formula to find out the surface area but I'm getting the point that in the formula why we take the integration limit as 0 to $2\pi$. Please, help me out! calculus

(a) The area of [a slice of the spherical surface between two parallel planes (within the poles)] is proportional to its width.. . . here's a rarely (if ever) mentioned way to integrate over a spherical surface. We assume the radius = 1.
Why it is not correct to say that the surface area of a sphere is: $$ 2 \int_{0}^{R} 2\pi r \text{ } dr ...
