Formula for volume of cylinder: pi*r^2*h
170 = 3.14*2.5^2*h
170=19,625*h
170/19.625 = h; h = 8.66 inches
Its a type of thermal expansion and described by fractions that represents the fractional increase length of a thin beam of a material exposed to its temperature increase of one degree celcious,"
The answer is (3,-4) because it machtes up with (-5,-4) and (3,4), so it (3,-4) is correct.
5 times amount of people has to be bigger than 2112
5(133+v)≥2112
distribute
665+5v≥2112
minus 665 from both sides
5v≥1447
divide both sides by 5
v≥289.4
yo can't have 0.4 volunterer
v≥290
has to have at least 290 volunteers
