Three undefined terms in geometry are
1 - Point
A point has no measurement or genuine size. A point is usually named with a capital letter. In the coordinate plane, a point is represented by (x,y).
2 - Line
A line has no thickness and its length extends in one measurement and goes on in both directions forever. A line is named by a single lowercase letter or by any two points on the line.
3 - Plane
A plane has no thickness and it extends indefinitely in all directions. A plane is named by a single letter (plane x) or by three non-collinear points (plane XYZ).
Answer:
The volume of the area not occupied by the tennis balls is 12.28 cubic inches.
Step-by-step explanation:
It is given that tennis balls with a diameter of 2.5in are sold in cans of three. the can is a cylinder.
Radius of ball = Radius of can = 
Height of can = 
The volume of sphere is

where, r is radius of sphere.
The volume of a tennis balls is



Volume of three tennis balls is

The volume of cylinder is

The volume of can is



The volume of the area not occupied by the tennis balls is
Volume = Volume of cylinder - Volume of three tennis balls
= 36.82 - 24.54 = 12.28 inches
Therefore, the volume of the area not occupied by the tennis balls is 12.28 cubic inches.
So it starts with 12 in the bacterial population. After 1 hour, 6 are added. After another hour passed, 9 are added. 12/1, 18/6, 27/9.
