Hey there!
To solve this problem, we will take a look at the FOIL Method.
<h3>What is "FOIL"?</h3>FOIL is a simple acronym that can be used to multiply binomials. It stands for:
F - Front
O - Outer
I - Inner
L - Last
See the image below for an example of how to use this in the given situation.
<h3>Apply</h3>Front: <em>Multiply the two terms out in the front.</em>
Outer: <em>Multiply the two terms on the outsides.</em>
Inner: <em>Multiply the two terms on the insides.</em>
Last: <em>Multiply the two terms in the back.</em>
Now, we add all of our answers from above:
Simplify by combining like terms:
There's our answer!

Answer:
The cream cone should be <u>6 inches</u>.
Step-by-step explanation:
Given:
A scoop of ice cream has 1.5 inch radius.
Now, to find the height of the cream cone.
So, we need to get the volume of scoop by putting formula:
Radius (r) = 1.5 inch.
Using the value π = 3.14.
<em>Thus, the volume of the ice cream scoop is 14.13 cubic inches.</em>
<em>So, to put all of the ice cream inside the cone.</em>
<em>We take the cream cone volume as the scoop volume.</em>
Let the height of cone be
<em>As, given radius is same.</em>
Now, to get the height of the cream cone we put formula of volume:
<em>Multiplying both sides by 3 we get:</em>
<em /><em />
<em>Dividing both sides by 7.065 we get:</em>
<u><em>Hence, the height of the cone = 6 inches.</em></u>
Therefore, the cream cone should be 6 inches.
