The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height. Since the cylinder and cone share the same radius and height, the volume of the cylinder before removing the cone is 54 in.³.
We can represent the volume of the cone as Vcone = (1/3)πr^2h.
After removing the cone, the remaining volume will be the volume of the cylinder minus the volume of the cone: Vremaining = Vcylinder - Vcone.
Since the cylinder and cone have the same radius and height, we can substitute r and h into the equations:
Vcylinder = πr^2h = 54 in.³
Vcone = (1/3)πr^2h
Now we can substitute these values into the equation for Vremaining:
Vremaining = Vcylinder - Vcone
= 54 in.³ - (1/3)πr^2h
We notice that πr^2h is common in both terms, so we can factor it out:
Vremaining = πr^2h(1 - 1/3)
= πr^2h(2/3)
So, the volume of the remaining amount is given by 2/3 times the volume of the cylinder:
Vremaining = (2/3) * 54 in.³
= 36 in.³
Therefore, the volume of the remaining amount is 36 in.³.

An engineer wants to know the volume of the following object composed of a hemisphere and a cone. She knows the height of the cone is equal to the diameter of the hemisphere, and the volume of the cone is 12 m3 . What is the volume of the whole object?(1 point) Responses There is not enough information to say. There is not enough information to say. 18 m3 18 m cubed 24 m3 24 m cubed 36 m3
To find the volume of the whole object, we need the dimensions of both the hemisphere and the cone. However, we are only given the volume of the cone, which is 12 m³.
Therefore, there is not enough information to determine the volume of the whole object.
