Ответ:
Density is defined as the ratio of mass to volume of an object. If the mass is already known, the volume of the cone is obtained using V equals one-third times pi times r squared times h.
For any substance;
Density = mass/volume
Since we are talking about a conic substance, the volume of a cone is given as V=1/3hπr².
Therefore, we need to apply the formula for volume of a cone in order to obtain the volume of the substance and subsequently its density using the mass given.
