Finding Dimensions of a Cylinder

The video tutorial explains how to determine the dimensions of a cylinder given its volume and a relationship between its height and diameter. The instructor defines variables for the radius, diameter, and height, sets up the volume equation, and solves for the radius. The dimensions are calculated, and the problem-solving process is recapped.

What is the given volume of the cylinder in the problem?

• 128 pi cubic feet

• 64 pi cubic feet

• 32 pi cubic feet

• 16 pi cubic feet

How is the height of the cylinder related to its diameter?

• Height is three times the diameter

• Height is equal to the diameter

• Height is half the diameter

• Height is twice the diameter

If the radius of the cylinder is x, what is the expression for the diameter?

• 4x

• 3x

• 2x

• x

What is the formula for the volume of a cylinder in terms of its radius and height?

• pi r^2 h

• pi r^3 h

• 2 pi r h

• pi r h^2

What is the expression for the height of the cylinder if the diameter is 2x?

• 4x

• x

• 2x

• 3x

What is the simplified expression for the volume of the cylinder in terms of x?

• 2 pi x^3

• 3 pi x^3

• 5 pi x^3

• 4 pi x^3

After dividing both sides by pi and 4, what equation do we get?

• x^3 = 8

• x^3 = 4

• x^3 = 2

• x^3 = 6

What is the value of x, the radius of the cylinder?

• 3

• 2

• 4

• 1

What is the diameter of the cylinder if the radius is 2 feet?

• 5 feet

• 4 feet

• 3 feet

• 2 feet

What is the height of the cylinder if the radius is 2 feet?

• 4 feet

• 10 feet

• 8 feet

• 6 feet
