WebMay 30, 2016 · Explanation: One common form of parametric equation of a sphere is: (x,y,z) = (ρcosθsinϕ,ρsinθsinϕ,ρcosϕ) where ρ is the constant radius, θ ∈ [0,2π) is the longitude and ϕ ∈ [0,π] is the colatitude. Since the surface of a sphere is two dimensional, parametric equations usually have two variables (in this case θ and ϕ ). WebSphere Surface Area Formula Sphere Surface Area = 4 x pi x radius squared. Sphere Surface Area = 4 π r 2 If inputs are in centimetres then the results are in square centimetres. If inputs are in inches then the results are in square inches. If inputs are in metres then the results are in square metres.
