Use the image to answer the question.

A cone is marked with a height of 6 centimeters and a diameter of 2 centimeters, both shown as perpendicular dotted lines. The slant height is marked as 4 centimeters.

What is the length of the cone?

The length of the cone can be found by using the Pythagorean Theorem.

The slant height is the hypotenuse of a right triangle formed by the height and the radius of the cone.

Let's call the radius of the cone r.

Using the Pythagorean Theorem, we have:

r^2 + 6^2 = 4^2

r^2 + 36 = 16

r^2 = 16 - 36

r^2 = -20

This is not possible, as the square of a real number cannot be negative.

Therefore, we cannot determine the length of the cone based on the given information.
