## How to Find the Slant Height of Cone?

A cone is a three-dimensional solid geometric figure having a circle at one end and a pointed edge at the other.

From the figure, 'r' is the radius of the cone, 'h' is the height of the cone, and 'l' is the slant height of the cone.

Using pythagoras theorem,** **

Slant height 'l' = √(r^{2} + h^{2})

**Solved Examples on Slant Height of Cone Calculator**

**Example 1:**

Find the slant height of a cone if the radius of the cone is 6 units and the height of the cone is 8 units?

**Solution:**

Slant height 'l' = √(r^{2} + h^{2})

= √(6^{2} + 8^{2})

= √36 + 64

= √100 units

= 10 units

Therefore, the slant of the cone is 10 units.

**Example 2:**

Find the slant height of a cone if the radius of the cone is 7 units and the height of the cone is 9 units?

**Solution:**

Slant height 'l' = √(r^{2} + h^{2})

= √(7^{2} + 9^{2})

= √49 + 81

= √130 units

= 11.40 units

Therefore, the slant of the cone is 11.40 units.

**Example 3:**

Find the slant height of a cone if the radius of the cone is 3 units and the height of the cone is 6 units?

**Solution:**

Slant height 'l' = √(r^{2} + h^{2})

= √(3^{2} + 6^{2})

= √9 + 36

= √45 units

= 6.70 units

Therefore, the slant of the cone is 6.70 units.

Similarly, you can try the slant height of cone calculator to determine the slant height of the cone if

1) Radius of cone = 10 units, height of the cone = 7 units

2) Radius of cone = 9 units, height of the cone = 13 units
