Hi. I'm having trouble with this question:
Oil is spilling from a platform at a constant rate Q and forms a circular spot of constant thickness 10cm. It is observed that when the radius is 100m the radius is changing at a rate of 5 m/hr.
a) How fast is the area of the spill changing at this instance?
b) calculate the value of Q.
b) I'm not sure what is Q...
does it have anything to do with
any help would be great!
