Answer:
3768
Step-by-step explanation:
The question is asking for the volume of the "cylinder" straw.
1cm = 10mm
30cm = 300mm
Volume of a cylinder = 
The radius is half of the diameter = 4/2 = 2
Radius squared is 4
Height is 300mm
1200mm * 3.14 = 3768
I am not very sure, since I am not that familiar with cylinders. Sorry if this is wrong.
Hope this helps :)
Have a great day!
Answer:
1) -2.13
2) 2.57
3) 33
Step-by-step explanation:
1)
3(8 + 5h) = -28 Distribute the 3
24 + 15h = -28 Subtract 24 from both sides of the equation
15h = -32 Divide both sides by 15 and round
h = - 2.13
2)
19 = 7(3n - 5) Distribute the 7
19 = 21n - 35 Add 35 to both sides of the equation
54 = 21n Divide both sides of the equation by 21
2.57 = n
3)
6s - 7s = -33 Combine the s's
-s = -33 Multiply both sides by -1
s = 33
