| Thermal resistances offered by both are different. | |

| Heat transfer by conduction depends on area, areas of sphere and cylinder are different. | |
| Kuru said: (Aug 22, 2013) | |
| The area of the cylinder is 2*3.14*r*l. The area of the sphere is 4*3.14*r^2*l. So will get different values of heat flux. |

| Simple answer is the area through which heat is transferring are different. | |

| Sphere and cylinder area's are different. | |
| Mrugesh said: (Mar 18, 2017) | |
| In cylinder, it follows logarithmic nature while in sphere it follows hyperbolic, don't it be same. | |
| Sulochana said: (May 24, 2017) | |
| I think both areas of sphere and cylinder are different. | |

| Regardless of the different areas, both are clearly said to be solid objects. How else will heat move around, Would you say its by radiation or convection? |
