    Surface area = 4 x Pi x R²

    = 4 x Pi x 4 ²

    = 201.06 inches

    Volume = (4/3) x Pi x R³

    = (4/3) x Pi x 4³

    = 268.08 cubic inches

    The surface area of a sphere = 4 π r²

    = 4 π 4²

    = 4 π 16

    = 64 π in.²

    The volume of a sphere = 4/3 π r³

    = 4/3 π (4) ³

    = 4/3 π 64

    = 256/3 π in.³
