If the radius of the circular region was 8 yards, what was the total length of the border, rounded to the nearest tenth of a yard?

i think it would be c

mark brainliest if im right

step-by-step explanation:

333.74 ! should be your answer for this question

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.
