Solve the given question:
Question: A circular hole of radius 8.468x 10-1 cm must be cut into the front panel of a display unit. The tolerance is 5.0 x 10-3 cm, which means the hole cannot differ by more than this quantity from the desired radius. If the actual hole is larger than the desired radius by the allowed tolerance,
A- What is the difference between the actual area and the desired area of the hole?
I know the answer but I want to know how to get that. Thanks in advance!
