Problem 5 Answer:
Answer:
diameter / 2 = radius
3 / 2 = 1.5
radius x radius x height x pi = volume
1.5 x 1.5 x 6 = 13.5
We don't multiply by Pi because it is already included

Answer:
Step-by-step explanation:
The volume of a cylinder is:
where is the radius and is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is
thus:
Dividing everything between pi:
We can see that the solution for this is
since
We have the radius, now we find the height:
