X + 3x + 4x = 56
8x = 56
x = 7
The shortest piece is 7 inches
The middle piece is 7*3 = 21 inches.
The longest piece is 4*7 = 28 inches
Check
7 + 21 + 28 = 56 It does check and the lengths are correct.
V=basearea times 1/3 times height
basearea=6<span>4π m2
hmm, they try to make it difficult
basearea=circle=pir^2
pir^2=64pi
divide by pi
r^2=64
sqrt
r=9
h is 4 les than 3 time r
h=-4+3(8)
h=-4+24
h=20
v=1/3*64pi*20=1280pi/3 m^3=1350.4

It doesn't give any answers? I think the first one is 14 the second one is -4 and the third one is 10
We would need to know how many students are in the class to properly answer the question.
Answer:
8
Step-by-step explanation:
3(2)-2(1-2) / 3-2
6+2 / 1
8/1
= 8
