How do i find the area of a sphere
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 ). WebReview how to find the surface area of sphere using 3.14 for pi.
