A rectangle with length n is inscribed in a circle of radius 9. Find an expression for the area of the rectangle in terms of n.

step-by-step explanation: 4 cause 2+2=4

answer:

125 yards

explanation:

75+50=125. that is my answer

c.)

step-by-step explanation:

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.
