Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :
or
We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
The term circumscribed means to limit, to restrain, or to surround. The figure circumscribed another figure means it is outside of that figure. On the other hand, the term inscribed means to draw the figure within another. This means that it should be inside another figure.
The given descriptions above are the exact opposite of the true meaning. Hence, the answer to this item is FALSE.
means you shade the part above the line, and
means you shade the part under the line.
If it has an equal bar under it, like this:
, then you also shade the line, by making it solid instead of dotting it.
