We can use the formula for the volume of a cone, which is V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone.

In this case, we have:

r = 6/2 = 3 inches (since the diameter is given as 6 inches)
h = 11 inches

Plugging these values into the formula, we get:

V = (1/3)π(3²)(11)
V ≈ 114.67 in³

Rounding to the nearest whole unit, the answer is:

O 115 in.³
415 in. 3 is answer
