Answer:
Step-by-step explanBecause many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

The answer is 6:
6+18= 24
24 divided by 4= 6
b=6
Y=-2/19x-13/19 is the answer
The problem is, I don't think that you estimated for letter a, so you can't do letter b.
So a circle has a total amount of 2π radians, now, divided even in 22 pieces, like the picture below, then
