Q. What is the cylindrical equation of the surface whose spherical equation is ρ=4
Convert to cylindrical coordinates: Convert the spherical equation to cylindrical coordinates. In spherical coordinates, ρ represents the distance from the origin. The cylindrical equation needs r (radial distance from the z-axis) and z (height).
Check for errors and relevance: Check the derived equation for errors and relevance to the question prompt. The equation r2+z2=16 correctly represents the cylindrical form of the given spherical equation ρ=4.
