Solve the each part of given problem:
Problem: As you eat your way through a bag of chocolate chip cookies, you observe that each cookie is a circular disk with a diameter of 8.50 ± 0.02 cm and a thickness of 8.5×102 ± 0.005 cm.
Part A: Find the average volume of a cookie?
Part B: Find the uncertainty in the volume of a cookie?
Part C: Find the ratio of the diameter to the thickness?
Part D: Find the uncertainty in the ratio?
I want help to calculate the uncertainty in the volume of a cookie.
