Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.
Answer:
27.50
Step-by-step explanation:
10±5±7.50=22.50
50- 22.50= 27.50
Answer:
34.75x
Step-by-step explanation:
Length of KL is 17 units
Given that;
L is mid point of KM
KL = 2x - 3
LM = x + 7
Find:
Length of KL
Computation:
We know that,
L is mid point of KM
So,
KL = LM
2x - 3 = x + 7
2x - x = 7 + 3
x = 10
So,
Length of KL = 2x - 3
Length of KL = 2(10) - 3
Length of KL = 20 - 3
Length of KL = 17 units
