Its urgent..
The height of a cone is 16 cm and the base radius is 12 cm. find slant height of cone.​

Answer 1

Answer:

20cm

Step-by-step explanation:

by using Pythagoras theorem

l=√r2+h2=122+162=20cm

Answer 2

Answer:

• 20 cm

GivEn:

• The height of a cone is 16 cm
• The base radius is 12 cm.

To Find :-

• The slant height of cone

Step-by-step explanation:

Let the slant height of the cone be x cm

The height, base radius and slant height forms a right angle triangle there.

So using the pythagorus theorem,

$\boxed{ \sf{Hypotenuse^{2} = Base^{2} + Height^{2} }}$

Here,

• Hypotenuse = Slant height = x cm
• Base = Radius = 12 cm
• height = 16 cm

Now, putting the values,

$\implies \sf \: {x}^{2} = {12}^{2} + {16}^{2}$

$\implies \sf \: {x}^{2} = 144 + 256$

$\implies \sf \: {x}^{2} = 400$

$\implies \sf \:x = \sqrt{400} = 20$

Therefore, the slant height = 20 cm
