Answer:

28,260.0 cm^3

Step-by-step explanation:

The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:

3.14(15^2)(40)

=3.14(225)(40)

=28260

Answer:

V ≈ 28,260 cm³

Step-by-step explanation:

V = πr²h where,

V = volume

r = radius

h = height

π = 3.14

To find the value of the radius, we take half of the diameter.

1/2(30) = 15

Now that we have all the values, we plug them into the equation and round.

V = (3.14)(15)²(40) = 28,260

V = 28,260
