Geometry of Cones
is a pyramid with
a flat base, curved wall
and pointy end
Cone in Geometry
apex
base
A Cone is made by rotating a triangle
radius
heig
ht
h
r r
h
base area + side wall area = π r2 + π r s = π r (r + s)
end areas + side wall area = 2(π r2) + 2π r h
= 2π r (r + h)
volume base area X height
= π r2 h
cone’s volume = 1 3
cylinder’s volume 1
2 3
