# A bucket, is in t

ABDC represents the frustum of the cone

Given:

Height GF = 42 cm.

In ΔABE & ΔCDE

AEB = CED (Common angle)

EDC = EBA (Corresponding angle)

So ΔABE & ΔCDE are similar by A.A. axiom of similarity

Since they are similar we can write

3EF = EF + 42

2EF = 42

EF = 21 cm

Height GE = 63 cm

Volume of Cone CDE =

Volume of Cone CDE = 2200 cm3

Volume of Cone ABE =

Volume of Cone ABE = 59400 cm3

Volume of Frustum of cone ABDC = Volume of Cone ABE- Volume of Cone CDE

Volume of Frustum of cone ABDC = 57200 cm3 = 57.2 liters
