In the cylindrical coordinate system, a point P in space is represented by the ordered triple (r, θ, z), where r and θ are polar coordinates of the projection of P onto

Cylindrical Spherical Cylindrical Coordinates x = r cosθ r = √x2 + y2 y = r sinθ tan θ = y/x z = z z = z Spherical Coordinates x = ρsinφcosθ ρ = √x2 + y2 + z2
PostNotes
z = z The reserve formula from Cartesian coordinates to cylindrical coordinates follows from the conversion formula from 2D Cartesian to 2D polar coordi- nates:

Note that, in cylindrical coordinates, the half-cone is given by z = √ r2 = r and the hemisphere is given by z = √ 8 − r2 To find the volume, we need to calculate
We note that this problem begs for cylindrical coordinates Indeed, z = 8) Calculate the centroid of the solid bounded by the cone z = √x2 + y2 and the planes
