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
Answer:
-273
Step-by-step explanation:
222- (99*5)
222-495
-273
Answer:
A. X=22
Step-by-step explanation:
x - 5 = 17
x =17 + 5
x = 22
Step-by-step explanation:
1..x=110/2. ( inscribed angle is half of central angle)
2..given,
in triangle DFE
angleDFE=angle DAE ( inscribed angle on same arc are equal)
angle DFE=55°
angle EDF= angle FED (base angle of isosceles triangle r equal)
now,
angle EDF+angleDFE+angle FED =180°{ sum of angle of triangle)
z+z+55=180°
2z=180-55
z=125/2
z=62.5°
3.. y=90°{ angle at circumference of circle by center is 90°}
hope it helps.
