14. Vertex is not
aligned at the
centre of base
Height of vertex is
in the center of the
circle
15. Formula
Volume of an oblique cone
= 1/3 (area of base)(cone
height)
= 1/3 Bh
B= πr2
16. Formula of oblique cone = 1/3 Bh
B= πr2
π = 3.142
r = 3 cm
H = 9 cm
Volume of oblique
cone
= 1/3 Bh
= 1/3 πr2h
= 1/3 (3.142) (3)2(9)
= 84.83 cm3
Example:
Given radius of base is 3 cm,
height of cone is 9 cm.
Calculate the volume of the
oblique cone.
18. Volume of an oblique cone
= 1/3 Bh
Volume of a right cone
= 1/3πr2 H
B= Area of base πr2 = Area of base
B = Area of base = πr2
Formula to find volume of oblique
cone and right cone is the same.
