Solve the all parts of given question:

Question: The quantity of charge q (in coulombs) that has passed through a surface of area 1.95 cm² varies with time according to the equation q = 3t3 + 7t + 6, where t is in seconds.

Part A: What is the instantaneous current through the surface at t = 0.950 s?

______A

Part B: What is the value of the current density?

______kA/m²

I want to know how to work this out step by step, not just the answer please.
