Answer:
418.00 cm³
Step-by-step explanation:
The volume of a cylinder is given by πr²h (r being the radius and h being the height)
The radius is half of the diameter: 6.4/2 is 3.2.
The height shown here is 13.
Instead of pi, the question says to use 3.14 instead of pi.
Putting these all together, you get 3.14×(3.2)²×13.
This can be expanded to 3.14×10.24×13.
From there, multiplying it all together gives you 417.9968 cm³.
The problem says to the nearest hundredth, so you want to round it to 2 decimal places. Since the 6 is above 5, it gets rounded up, leaving you with 418.00 cm³.
