<h3>What is Essential and Nonessential Elements?</h3>
Nonessential elements as the name implies are elements which are not necessary for the functional routine of the body and hence are not included in diets.
Essential bulk elements are elements which are needed for the proper functioning of the body and hence are required in relatively large amounts.
Essential trace elements are required in minute quantities in the body.

The total area of the figure will be 245 sq. in.
<h3>Total area of a cylinder</h3>
The figure is a cylinder and the total area of a cylinder is given by the formula below:
Total Area of a cylinder = 2πrh+2πr^2
Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.
In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:
Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)
= 245 sq. in.
Thus, the total area of the solid figure is 245 sq. in.
