A student is trying to calculate the density of an ice cream cone. She already knows the mass, but she needs to determine the vo
lume 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
In any chemical reaction, the mass of the products must equal the mass of the reactants. The mass of product B is the same as the combined mass of Reactant A and H₂O.
