Surface area of sphere using circumference
WebFor the radius of the sphere d, the arc length id d θ, where sin ( θ) = r / d. The area of the "circle" is then π d 2 θ 2. My mistake. Here is the solution: Suppose you call r the length of the arc along the sphere, and x the radius in the plane. At a position l along the arc, x = d sin ( θ), where θ = l / d.
