  1. Answer:

    let no, of sphere be N

    by given, volume of the cylidrical= N×volume of sphere

    radius of cylinder =14cm

    height= 21cm

    volume pai r^2h=22/7×21×14×14

    = 12936cm^3

    radius of sphere =3.5cm

    volume = 4/3×22/7×3.5×3.5×3.5= 179.66cm^3

    N=129366/179.66

    N=72

    Step-by-step explanation:

    let no
