Answer:
50 violins were sold
Step-by-step explanation:
Volume of a cylinder:
V = pi * r^2 * h
where "r" is the radius and "h" is the height.
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
<h3>Midline, Amplitude and Period</h3>
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
