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:
8. x=450
Step-by-step explanation:
I can only answer 8 sorry qwq
The answer is -37.
So, let's break this down:
(7 - 10 = -3)
[45 ÷ 3 = 15]
[15 x -3 = -45]
4 x 2 = 8
8 + -45 = -37
