To determine the volume of a cylinder, you need to use the formula V = pi*r^2*h
To calculate the radius, all we have to do is divide the diameter by 2.
7.5/2 = 3.75
Now we can plug in the values.
V = 3.14 * 3.75 * 11 = 485.7 (This answer is rounded to the nearest tenth. Original answer: 485.71875)
Your answer is 485.7
