3 days ago · To prove that the surface area of a sphere of radius r r is 4 \pi r^2 4πr2, one straightforward method we can use is calculus. We first have to realize that for a curve parameterized by x (t) x(t) and y (t y(t ), the arc length is. S = \int_a^b \sqrt { \left (\frac {dy} {dt}\right)^2 + \left ( \frac {dx} {dt}\right)^2 } \, dt.
