In a solid hemisphere of radius 10 cm
WebUse spherical polar coordinates r, θ, φ to find the CM of a uniform solid hemisphere of radius R, whose flat face lies in the xy plane with its center at the origin. Before you do this, you will need to convince yourself that the element of volume in spherical polars is dV = r²dr sinθ dθ dφ.
