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 = $\pi r^2h$

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!

Multiply both sides of the each equation in order to get the coefficient to be an integer.

monitta

$45= \frac{1}{2}a-3 //+3 \\ 48= \frac{1}{2} a// : \frac{1}{2} \\ 48: \frac{1}{2}=a=\ \textgreater \ 48*2=a=\ \textgreater \ a=96$
Hope that helps.Have a nice day!! ^^
