Question

If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter. What is the volume of the tank? Assume that 3.14 is the value for pi.

Answer 1

The volume of the tank is
`84.78\ m^(3)`

Explanation:

we know that

The volume of a cylinder is equal to

`V=\pi r^(2)h`

In this problem we have

`r=6/2=3\ m` -----> the radius is half the diameter

`h=3\ m`

substitute

`V=(3.14)(3^(2))(3)=84.78\ m^(3)`

Answer 2

h = 3 m, d = 6 m , so: r = 3 m;
The volume of the tank is:
V = r² π h = 3² · 3.14 · 3 = 9 · 3.14 · 3 = 27 · 3.14 = 84.78 m³
