Astudent is trying to calculate the density of an ice cream cone. she already knows the mass, but she needs to determine the volume as well. which of the following formulas can be used to calculate the volume of the cone?

v equals four-thirds times pi times r cubed
v equals one-third times pi times r squared times h
v = s3
v = πr2h

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.
