What is the volume of this cylinder?

dalvyx [7]

Answer:

12762.72 cubic meters

Step-by-step explanation:

The volume of a cylinder is denoted by the formula: $V=\pi r^{2} h$ , where r is the radius and h is the height.

Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.

Now substitute these values into the equation:

$V=\pi *(18.8^2)*11.5=3.14*(18.8^2)*11.5=12762.72$ cubic meters

Hope this helps!
