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:
17 cups i believe. lemme check. naw its 13
Step-by-step explanation:
Area of shaded region=π(R²-r²)
R=Bigger radius
and r=smaller radius
∴π(10²-5²)
π(100-25)
π75
let's take π=3.14
3.14×75=235.5 cm²
Answer:
36.8 *36 8/10 of 36 4/5
Step-by-step explanation:
2/5x(-1/2)= -2/10
37+(-2/10)=36.8
Answer:
so the answer would be he drives 8 hrs she drives 4 which equals 12
Step-by-step explanation:12 divided by 2 is six so then u take away 2 from moniques hrs and add them to tonys and u get 8 for him and 4 for her
