The answer is 15 in³.
The volume of the cone is:

where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone
The volume of the cylinder is:

where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone
Since <span>the cone fits exactly inside of the cylinder, they have the same radius and the height:
r</span>₁ = r₂
h₁ = h₂
Also:
V₁ = 5
Now, let's write two volume formulas together:

<span>

</span>
We can include V₂ into V₁:

Jake puts 6 stamps in his book every day.
30/6= 5
Jake put stamps in the book for 5 days.
So, Dan puts 5 stamps in the book every day.
5*5= 25
Dan has 25 stamps when Jake has 30.
I hope this helps!

Answer:

Step-by-step explanation:
Given
-- Rate
-- Principal
-- Time
Required
Determine the compound interest
First, we calculate the Amount (A)


Express % as decimal



The compound interest (C) is then calculated as:
i.e. Amount - Principal
