In a right circular cone, the slant height is 13cm. Where

To determine

**To find:**

The altitude of the cone.

Explanation

In a right angle triangle,

1) The side PQ, which is opposite to the right angle PRQ is called the hypotenuse.

(The hypotenuse is the longest side of the right triangle.)

2) The side RQ is called the adjacent side of angle

3) The side PR is called the opposite side of angle

Hence, the sine ratio for an acute angle is

**Given:**

In a right circular cone, the slant height = 13 cm and

Consider the cross section of the right circular cone.

From, the given diagram,

Hypotenuse, AB = 13 cm

Let

We have to find the altitude of the cone i
