Answer:
Step-by-step explanation:
Let h be the cylinders height and r the radius.
-The volume of a cylinder is calculated as:
-Since the cone is within the cylinder, it has the same radius as the cylinder.
-Let be the height of the cone.
-The area of a cone is calculated as;
The volume of the solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:
Hence, the approximate area of the solid portion is
The equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A).
<h3>What linear equation best fits the scatter plot?</h3>
The equation of the line is represented by a polynomial of the form y = m · x + b, where m is the slope of the line and b is the intercept of the line. The slope is equal to the change in the <em>dependent</em> variable (Δy) and in the <em>independent</em> variable (Δx) and the intercept is the <em>vertical</em> distance of the line with the origin when x = 0.
In accordance with the picture, we notice that the scatter plot indice that Δy < 0 and Δx > 0 and therefore, m < 0. Besides, the intercept of the equation of the line must be greater than zero. Thus, the equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A)
