We can define the base of each equilateral section as

since this is the distance from the x-axis to the function

.
An equilateral triangle's area can have a function defined solely by the base. Since all sides are equal, the height of the triangle can be found via pythagorean theorem as:

But we know that the base

is a function of x. We also can then state that Area

is also a function of x. Specifically:

.
Then if we integrate the area function A(x) from 0 to pi, we get the total volume:
C, positive self-talk
If you tell yourself you can do something, you will.
Answer:
The correct option is;
B. The photo is a digital representation of the analog painting
Explanation:
The forming of a encoded digital representation of the an object's physically as visually or observed characteristics is known as digital imaging such that there is an implied application of digital processing to the (otherwise analogue) image such as printing, display, storage, or compression of the original image.
With a digital image, copies can be made of the captured image an infinite amount of time while still maintaining the quality of the original copied image.
A painting made by the use of pencils, paints, canvases, and films is known as an analog art or painting.
Answer: vermount and Middle East
Today he is best remembered for his contribution of Man and Nature. The work incorporates observations he made as a youth in Vermont, as well as on his travels in the Middle East. He was the first to suggest that human beings were agents of change, or "disturbing agents." The conventional idea held by geographers of the day, Arnold Guyot and Carl Ritter, was that the physical aspect of the earth was entirely the result of natural phenomena, mountains, rivers, oceans. No one had ever turned to the study of the earth as the home of humankind. Marsh was the first to describe the interdependence of environmental and social relationships.
Explanation:
He was a good diplomat. But we remember Marsh the scholar. He was a student of Scandinavian languages. As a philologist, he wrote an important book on the character of the English language. He was an art collector. As a scientist, he gathered reptiles for the Smithsonian. He was instrumental in the Army's attempt to use the camel in the American Southwest
Over the next few years, Marsh gave a series of lectures on the English language. In 1861, President Lincoln appointed him the first United States minister to the kingdom of Italy, and on April 27, at the age of 60, he set sail, with Caroline, for Europe. In Italy, he found time and capacity for his environmental concerns. He made several fruitful excursions to the Alps where he studied glaciers, moraines, and avalanches. Marsh witnessed Alpine erosion and the devastating contribution of grazing and deforestation, in disastrously accelerating natural erosive processes. In 1862, he began working on the manuscript for Man and Nature, a pioneering study in ecology and conservation.
