1. Suppose a water tank in the shape of a right circular cylinder is thirty feet high and eight feet in diameter.
a) How much sheet metal was used in its construction of the whole water tank? Round to the nearest hundredth.
Area of sheet metal =
b) How much water will the tank hold in ft3? Round to the nearest hundredth.
Volume of tank =
2.
he borders of the state of Utah have approximately the lengths shown on the map. The United States Department of the Census project projects that Utah will have a population of 2,990,094 in the year 2020. Based on this information, find the population density of Utah in 2020. Round your answer to the nearest whole number.
Area of Utah =
Population Density =
+37152 Sheet metal n the tank:
TWO ends have area of pi r^2 2 x pi 4^2
PLUS the circumference x height = pi x d x 30 = pi x 8 x 30 Add reds together to get surface area of sheet metal.
Volume of cylinder = pi r^2 h = pi 4^2 x 30 = ......
Utah question does not have map diagram.....
+37152 Water can get out from the top......evaporation! The ends closed also prevent contamination of the tank contents. Tanks are often closed on both ends.....like a tanker truck...or the LP gas tank at your house (perhaps)....
