A bucket, is in t
ABDC represents the frustum of the cone
Height GF = 42 cm.
Radius GB = 30 cm.
Radius FD = 10 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
