Step-by-step explanation:
The General Slicing Method is given by
<em>Suppose a solid object extends from x = a to x = b and the cross section of the solid perpendicular to the x-axis has an area given by a function A that is integrable on [a, b]. The volume of the solid is</em>
Because a typical cross section perpendicular to the x-axis is a square disk (according with the graph below), the area of a cross section is
The key observation is that the width is the distance between the upper bounding curve and the lower bounding curve
The width of each square is given by
This means that the area of the square cross section at the point x is
The intersection points of the two bounding curves satisfy , which has solutions x = ±1.
Therefore, the cross sections lie between x = -1 and x = 1. Integrating the cross-sectional areas, the volume of the solid is
Hello!
We know that any given percentage can be expressed as a fraction with a denominator of 100, as follows:
Because we want to find 25% of the celery sticks, we can convert this percentage into the following fraction:
= 
Now multiply this reduced fraction by the number of celery sticks:
44 × = 
The fraction can be reduced to a value of 11. We have now proven that 11 celery sticks received peanut butter.
I hope this helps!
