Answer:
D
Step-by-step explanation:
In Maths, axioms are basically set of propositions from which we can derive true statements from logic. Then these statements are known as theorems.
Hence, defining theorem in an axiomatic way means that a statements that we derive from axioms (propositions) using logic and that is proven to be true.
From the answer choices, we see D goes with this, hence D is the correct answer.
The answer is 9/10 but also 0.9
The number of tennis ball that will fill the room is <u>1,371 tennis balls.</u>
<em><u>Given</u></em>:
Diameter of ball (d) : 2 inch
Radius (r) = half of diameter = 1 inch
Dimension of room = 20ft by 16ft by 18ft
Number of balls that will fill the room = Volume of each ball/volume of the room
Volume of the ball = volume of a sphere = 
Where,
r = 1
let 
<em>Substitute</em>:

Volume of the room = 

Therefore:
number of tennis balls that will fill the room = 
Therefore, the number of tennis ball that will fil the room will be <u>approximately 1,371.</u>
