Question

A conical tent is 9 m high and the radius of its base is 12 cm. Find the slant

height of the cone.​

Answer 1

Answer:

The answer is 15cm.

Step-by-step explanation:

Given: A conical tent is 9 m high and the radius of its base is 12 cm.

To find: Find the slant height of the cone.​

Concept: The formula which will be used:

$I = \sqrt{r^{2} +h^{2} }$ , where,

• I= Slant height of the cone
• r= radius of a cone
• h= Height of a cone

Calculation:

So, here we know the formula of the slant height, and now the height of the cone is given = 9cm, and then its base which is 12 cm, which is a radius

so, we put the formula,

$I = \sqrt{12^{2} +9^{2} }$

I = $\sqrt{144+81}$

$I = \sqrt{225}$

I = 15 cm

Therefore, the slant height of the cone is 15 cm.
