    Step-by-step explanation:

    Lets assume that a sphere with greater radius = R = 5cm

    And a sphere with smaller radius = r = 4cm

    Volume of a sphere = 4/3 π * r³

    To find the volume of a sphere with radius 5.

    Put the value in the formula.

    =4/3π * r³

    =4/3π * (5) ³

    5³ = 5*5*5=125

    =4/3π * 125

    =4/3 * 3.14 * 125

    =1570/3

    =523.3 cm³

    Now find the volume of sphere with radius = 4

    4/3π*r³

    =4/3π * 4³

    4³ = 4*4*4=64

    =4/3*3.14*64

    =803.84/3

    =267.9cm³

    Now to find the space between the spheres subtract the volume of smaller sphere from the volume of larger sphere.

    We can write it as:

    Space between the spheres = Volume of larger sphere - Volume of smaller sphere

    = 523.3 cm³ - 267.9cm³

    = 255.4cm³ ...
