A conical vessel, with internal radius 5 cm and height 24 cm, is full of water. The water is emptied into a cylindrical vessel with internal radius 10 cm. Find the height to which the water rises.
A2 cm
B4 cm
C1 cm
D3 cm
✓ Correct Answer: A — 2 cm
Vol_cone = 1/3 * π * 5² * 24 = 200π. Vol_cyl = π * 10² * h = 100πh. 100πh = 200π => h = 2 cm.
