Example Question #71 : 3 Dimensional Geometry

Find the volume of a cylinder with a radius of 7in and a height of 4in.

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 radius is 7in. We know the height is 4in. So, we substitute. We get

Example Question #71 : 3 Dimensional Geometry

The answer is:  

Example Question #632 : Geometry And Graphs

Find the volume of a cylinder with a diameter of 6in and a height of 8in.

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 6in. We know the diameter is two times the radius. Therefore, the radius is 3in. We know the height of the cylinder is 8in. So, we can substitute. We get
