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

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

Answer 2

Answer:

The volume of the tank is $84.78\ m^{3}$

Step-by-step 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

$V=(3.14)(3^{2})(3)=84.78\ m^{3}$
