a.12.56
b.84.82
Step-by-step explanation:
you have to do 3 * 3 * π * 3 and you get 12.56
with b you have to do π * 1 * 1 * 4 and you will get 84.82
Answer:
a. [tex]V=84.82\ in^3[/tex]
b. [tex]V=12.57\ in^3[/tex]
Step-by-step explanation:
The formula for calculating the volume of a cylinder is the following:
[tex]V=\pi r^2h[/tex]
Where r is the radius of the cylinder and h is the height of the cylinder
So for the first cylinder we have to:
r = 3 inches, h = 3 inches
[tex]V=\pi (3)^2(3)[/tex]
[tex]V=27\pi[/tex]
[tex]V=84.82\ in^3[/tex]
For the second cylinder we have to:
r = 1 meter, h = 4 meters
[tex]V=\pi (1)^2(4)[/tex]
[tex]V=4\pi[/tex]
[tex]V=12.57\ in^3[/tex]
