thx for help and please attach with detailed explanation

A solid, spherical conductor has a radius of 5 cm. It is enclosed by a thin concentric conducting shell of radius 6 cm. The space between the sphere and shell is filled with a dielectric material of relative permittivity 250. What is the capacitance of this object? Select one or more: O a. 45.547 microfarad O b. 8.3449 nanofarad O c. 45.843 microfarad O d. 14.456 picofarad O e. 56.523 nanofarad O f. 1.4567 millifarad O g. 4.7564 picofarad O h. 3.7684 microfarad
