A cylindrical container is filled with ice-cream, whose diameter is 10cm and the height 17.5cm. The whole ice-cream is distributed to 12 children in equal cones having hemispherical tops. If the height of the conical portion is five times the radius of it's base, find the diameter of the ice-cream cone.
Answers
The diameter of the ice-cream cone is 3.718 cm
Step-by-step explanation:
Diameter of cylindrical container = 10 cm
Radius of cylindrical container =
Height of cylinder = 17.5 cm
Volume of cylindrical container =
Volume of cylindrical container =
Volume of cylindrical container =
The whole ice-cream is distributed to 12 children in equal cones having hemispherical tops
So, Amount of ice cream for 1 student =
Amount of ice cream for 1 student =
Let the radius of hemisphere be r
The height of the conical portion is five times the radius of it's base
Height of conical portion = 5r
Volume of 1 cone = Volume of cone+ Volume of hemisphere
Volume of 1 cone =
Volume of 1 cone = ---A
Amount of ice cream for 1 student = --B
So, Equate A and B
So, Radius of cone is 1.859 cm
Diameter =
Hence the diameter of the ice-cream cone is 3.718 cm
