I need picture because I need to understand it more
The method of heat transfer that does not require a medium is radiation. Heat may be transmitted across void space through thermal radiation, commonly known as infrared radiation.
No mass is transferred and no medium is required during radiation. Radiation is the only method of heat transmission that does not need a substance, such as the heat released by the sun or the filament of a light bulb. There is no material medium necessary for the propagation of electromagnetic waves, often known as radiation. Only in a vacuum can we observe the perfect transfer of energy, because when radiation travels through material, part of its energy is lost. (Subject to the material property)
Conversely, in the instance of Conduction.

Answer:
Twice the radius
As with circles, the diameter of a sphere is twice the radius. C = πD or 2πr. As with circles, the circumference of a sphere is equal to π times the diameter. Since the diameter is twice the radius, we can also say that the circumference is twice the radius times π. V = (4/3)πr3
