Answer: 1306.5 m^3
Step-by-step explanation:
1. The formula for the volume of a cylinder is: V=
r^2h
2. If you substitute the values into the equation, you get
V = pi * 5.7^2 * 12.8 = 1306.5
3. 1306.5 is already to the nearest tenth, so that is the answer.
You have to do 21+8+11=40. So 40 is the answer. Hope this helps.
It depends on what kind of pencil it is.
