Asap quiz ! in cold climate areas, trucks are used to disperse salt on the roads in order to de-ice the roads, making them safe for travel. in some cases, cone-shaped sheds, made in three different sizes, are used to store the salt during off-season, or until the roads need to be de-iced. use the formula for the volume of a cone to complete the table below. use 3.14 for . volume radius diameter heightsmall ? ? 15.2 1.8medium 301.2 10.95 ? ? large ? 13.7 ? 3.0

you can not solvr this without numbers

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
