Answer: 394 cm3
Step-by-step explanation:
volume of cylinder - volume of 5 balls=extra volume
voc=πr2h=1181.09
pi=22/7
r=3.35
h= 5 x diameter of ball=33.5 (diameter = 2r)
vo5b=5(4/3πr3)=787.4
r=3.35
ev=voc-vo5b
=393.69
ROUND TO 394
2:7
Because you have to add all the students.
4+ 10 = 14
Boys to students = 4:14
Simplest form: 2:7 because two can go into 4 two times and can go into 14 seven times.
