CH-21-001 · Cone transfer, cylinder capacity and overflow
A full conical vessel has radius 6 cm and vertical height 17 cm. Its contents are poured into an initially empty cylinder of radius 7 cm and height 9 cm. This is repeated 7 times, using a full cone each time. Find the final water depth in the cylinder and the volume of water that overflows, in litres. Give both answers to 2 decimal places.
3D Shapes: Cone-to-Cylinder Volume Transfer
Booklet p. 39 & p. 40
Method
1) Total poured volume = n × (⅓πr²h)
2) Cylinder capacity = πR²H
3) Compare to find depth and divide overflow cm³ by 1000 for litres
Worked Example (CH-21-001)
1)
Cone volume = .
2)
Multiply by 7 for total water volume.
3)
Cylinder capacity = .
4)
Compare supplied volume with capacity; final depth is the smaller of container height and volume ÷ base area.
5)
Depth 9.00 cm.
6)
Overflow = max(0, supplied volume − capacity); divide cm³ by 1000.
7)
3.10 litres.
Ans =
Depth 9.00 cm; overflow 3.10 litres.
