Answer:
Scientific notation is a way to make these numbers easier to work with. In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal.
The cone is a three dimensional shape, and the value of the height of the cone is 27 inches
<h3>How to determine the height?</h3>
The given parameters are:
- Shape = Cone
- Volume, V = 45 in^3
- Base area, B = 5 in^2
The volume of the cone is calculated using:

So, we have:

Divide both sides by 5

Multiply both sides by 3
h = 27
Hence, the value of the height of the cone is 27 inches

Let, the number = x
x * 75% = 354
x * 0.75 = 354
x = 354 / 0.75
x = 472
In short, Your answer would be 472
Hope this helps!
you start by adding any 2 numbers and then multiplying the sum by 3
