A) Answer the question shown in the image 

Consider a hollow sphere of internal radius 0.150 m and external radius 0.600 m. The sphere is made of a material whose thermal conductivity is given by the following mathematical relationship: k = kor %3D Where ko = 1.50 W / m²K and r is the radial distance measured from the center of the sphere. If the inner part of the sphere is at 20 ° C and the outer part of the sphere is at 100 ° C. Calculate: A) The radial heat flow through the sphere
