Question

The number of cubic feet of water in a curved container can be approximated by v = 0.95h2.9. use a calculator to find the amount of water in the container when h = 7.5 feet. round to the nearest tenth.

Answer 1

The first thing we must do for this case is to rewrite the expression of the volume correctly.
 We have then:
 v = 0.95 * h ^ 2.9
 Substituting the value of h we have:
 v = 0.95 * (7.5) ^ 2.9
 v = 327.6432831
 round to the nearest tenth:
 v = 327.6 feet ^ 3
 Answer:
 the amount of water in the container when h = 7.5 feet is:
 v = 327.6 feet ^ 3
