Hi, Can you help with both parts please, I am really confused how to go about this question. A cylindrical disk of radius r = 11.5 cm and thickness H = 4.5 cm is made from a material that has a resistivity ? = 1.6 10-5 ??m. We wish to determine the resistance across the diameter of the cylinder.

Part A: Integrate over the diameter of the cylinder to create an equation for the resistance in terms of ?, H, and r.

Part B: Calculate the resistance for the cylinder, in units of m?.

y A B X dx
