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!
Y-intercept is (0,-7) x-intercept is (14,0)
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
