The formula to solve a cylinder is V=πr²h
So, round pi to 3.14
We must plug in for the radius (r) in this equation. To do this, we must half up the diameter, 5. 5/2 = 2.5
6 is height
V=3.14 * 2.5² * 6
V=117.81 we must round though to tenth, and that would be:
Answer V=117.8m³
Answer: two cans
Step-by-step explanation:
area of the long side walls
20 * 10 = 200
area of short side walls
15 * 10 = 150
two walls for each so 200 +150 = 350
so he needs two paint cans
