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?

blank centimeters$$
The length of the cone can be found using the Pythagorean theorem. The height (6 cm) and slant height (4 cm) form a right-angled triangle. Let's name the length of the cone as "l". According to the Pythagorean theorem, we have:
l^2 = h^2 + r^2
l^2 = 6^2 + 1^2
l^2 = 36 + 1
l^2 = 37
l = √37
Therefore, the length of the cone is approximately √37 centimeters.
