Question

a cylinder is within the cube touching all the vertical faces a cone is inside the cylinder it if the height are the same with the same base find the ratio of their volumes

Answer 1

Let the edge of the cube be a.
Height of the come and cylinder will be a and the radius of their bases will be a/2
Volume of cube = a³
Volume of cylinder = πr²h = π a³/4 = 11/14 a³
Volume of cone = 1/3 πr²h = π a³/12 = 11/42 a³

Ratio = a³ : 11/14 a³ : 11/42 a³ = 1 : 11/14 : 11/42

Answer 2

this is the ans..........
