Katherine is using a cone to fill a cylinder with sand. If the radii and height are equal on both objects, and Katherine fills the cone to the very top, how many cones will it take to fill the cylinder with sand? Complete the explanation. It will take cones to fill the cylinder with sand. Because the volume formula for a cylinder is V = πr2h, and the volume formula for a cone is V = 1 πr2h, the volume of a cone is 1 the volume of the cylinder. Question solved general 5 months ago 7998
