• Hexahedron

• Cylinder

• Cube

What is the base shape of a cylinder?

• Square

• Circle

• Rectangle

• Triangle

How do you find the volume of a cylinder?

• Base area / Height

• Base area × Height

• Base perimeter × Height

• Base area + Height

What is the formula to calculate the area of a circle?

• 2r^2

• πd

• 2πr

• πr^2

If a cylinder has a radius of 10 units, what is the area of its base?

• 314 units^2

• 100 units^2

• 100π units^2

• 200π units^2

What units are used to express the volume of a 3D object?

• Square units

• Linear units

• Cubic units

• Quadratic units

If the diameter of a cylinder is 18 units, what is its radius?

• 36 units

• 4.5 units

• 18 units

• 9 units

For a cylinder with a radius of 6 inches and height of 10 inches, what is the volume?

• 60π cubic inches

• 600π cubic inches

• 120π cubic inches

• 360π cubic inches

Why is volume always expressed in cubic units?

• Because it measures surface area

• Because it involves three dimensions

• Because it is easier to calculate

• Because it is a linear measurement
