Example Question #51 : 3 Dimensional Geometry

Find the volume of a cylinder with the following measurements:

Diameter:  8in

Height:  12in

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cylinder, we will use the following formula:

where r is the radius, and h is the height of the cylinder.

Now, we know the diameter of the cylinder is 8in. We also know the diameter is two times the radius. Therefore, the radius is 4in. 

We know the height of the cylinder is 12in.

Knowing all of this, we can substitute into the formula. We get

Example Question #13 : Volume Of A Cylinder

Find the volume of a cylinder with a height of 14in and a diameter of 8in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cylinder, we will use the formula

where r is the radius, and h is the height of the cylinder.

Now, we know the height of the cylinder is 14in.

We know the diameter of the cylinder is 8in. We also know the diameter is two times the radius. Therefore, the radius is 4in.

Knowing all of this, we can substitute into the formula. We get

Example Question #14 : Volume Of A Cylinder

What is the volume of a cylinder if the base diameter is 10, and the height is 5?

Possible Answers:

Correct answer:

Explanation:

Write the formula for the volume of a cylinder.

The radius is half the diameter.

Substitute the terms in the equation.

The answer is:  

Example Question #61 : 3 Dimensional Geometry

Example Question #16 : Volume Of A Cylinder

What is the volume of a cylinder with a base circumference of  and a height of ?

Possible Answers:

Correct answer:

Explanation:

To determine the radius of the base, write the circumference formula.  The base represents a circle.

Substitute the circumference.

Divide by  on both sides.

Write the formula for the volume of a cylinder.

Substitute the radius and height.

The answer is:  

Example Question #17 : Volume Of A Cylinder

Find the volume of a cylinder with the following measurements:

Diameter:  10in

Height:  14in

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cylinder, we will use the following formula:

where r is the radius, and h is the height of the cylinder.

Now, we know the diameter of the cylinder is 10in. We also know the diameter is two times the radius. Therefore, the radius is 5in.

We know the height of the cylinder is 14in.

Knowing all of this, we can substitute into the formula. We get

Example Question #11 : Volume Of A Cylinder

Find the volume of a cylinder with a height of 11in and a diameter of 6in.

Possible Answers:

Correct answer:

Explanation:

To find the volume of a cylinder, we will use the formula

where r is the radius, and h is the height of the cylinder.

Now, we know the height of the cylinder is 11in.

We know the diameter of the cylinder is 6in. We also know the diameter is two times the radius. Therefore, the radius is 3in.

Knowing all of this, we can substitute into the formula. We get

Example Question #61 : 3 Dimensional Geometry
