??Jack has two spheres one has radius of 12 and the other has a diameter of 12. What is the difference between two spheres?

  1. Bosnian



    Radius of first sphere R1=12

    Radius of second sphere R2=D2/2=12/2=6



    Area of sphere=4*pi*R^2

    Area of first sphere A1=4*pi*12^2=

    Area of second sphere A2=4*pi*6^2



    Volume of a sphere:


    Volume of first sphere:

    Volume of second sphere:




    First sphere have 2x larger Radius, 4x larger Area and 8x larger Volume
