The Pyramid and Mountain

Hi Lollipops lovers..

I am Kiki, a Mathematician from Indonesia. When, we observe the basic idea of The Pyramid and Mountain are the same. Do you agree with me? They have the top point.

Are they, The Pyramid and Mountain, look similar, aren't they? Actually, the shape of the mountain is cone. The Pyramid is a cone that has 4 slant height only instead of infinite slant height. 

Parts of a cone

In 2-Dimentional shape both The Pyramid and Mountain looked as a triangle in 360° of angle of view arround it.

Both pyramid and cone has similar volume formula;

Like a square is a special type of rectangle beacuse it has all the properties of rectangle, plus all sides are equal in length. A pyramid is a special type of cone.
