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
Sati [7]
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

What is the volume, in cubic M, of a cylinder with a height of 13M and a base radius of 3M, to the nearest 10th Place?
irina [24]

Answer:

The volume of the cylinder is 367.6 M^3

Step-by-step explanation:

Mathematically, we have the volume of a cylinder calculated as follows;

V = pi * r^2 * h

r is the base radius given as 3 m

h is the height given as 13 m

So, we have the volume as;

V = 22/7 * 3^2 * 13 = 367.6 M^3
