Know the formulas for the area and circumference of a circle to use them to solve problems; give an informal derivation of the relationship between the circumference and area of the circle. a) a circular plate has a diameter of 9 inches. what is the area of the plate?
round you answer to the nearest hundredth

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

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.

my answer was deleted because it was to vague the answer is 12.76 becuase its in the hundreths place. john
