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>

Answer:
it is option 2 which is height or altitude^2 + base^2=x^2
Solution:
<u>We know that:</u>
- Given diagonals: LN and MP
- LN and MP must be equal because they are diagonals of LMNP.
- LN = 4x + 3
- MP = 8x - 9
<em>Since LN and MP must be equation</em>, <u>equation formed:</u> 4x + 3 = 8x - 9
<em>Let's simplify the equation to find x.</em>
<u>Subtracting 4x both sides.</u>
<u>Add 9 both sides.</u>
<u>Divide 4 both sides.</u>
<em>Now, let's find the length of each diagonal.</em>
