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

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
