A cylinder of radius 14cm contains water.A metal solid cone of base radius 7cm and height 18cm is submerged into water. Find the change in height of the water level in the cylinder

Answer 1

the water displaced has volume
v = π/3 r^2 h = π/3 * 7^2 * 18 = 2401π cm^3
so now you can find h using
196πh = 2401π
