Explain what appreciation and depreciation are and give an example of an item that appreciates and and example of an item that
depreciates over time.

Appreciation is when the price of an asset goes up in value. Investors that purchase commodities or real estate want the price of these investments to go up over time. For instance, if you purchase stock at $10 and it goes up to $15 in a month and then $20 after two months, the stock is said to have appreciated by $10, or 100 percent. There are many reasons for a stock to appreciate in value, including inflation, lack of supply, or an increase in demand. Depreciation has two meanings in the world of finance. It refers to the process of writing off the cost of business equipment over time, and not solely in the year the asset was incurred. Depreciation also refers to the devaluation of assets over time. As assets lose value, either due to lower prices, increased supply, or decreased demand, they are said to depreciate in value. In the latter case, depreciation is the opposite of appreciation. Assets are constantly increasing and decreasing in value. Those assets with a ready exchange, such as stocks or commodities, increase and decrease in value daily, especially if they are traded by a large investor group. Assets which are not traded on a national exchange, like real estate or equipment, may lose or gain value over time; however, it is up to the holder of the asset to determine the current market price, which can be difficult without a ready market.

The lateral area of the cone is given by:
 Al = pi * r * g
 Where,
 r: radius of the base
 g: slant height
 Substituting values we have:
 120 = 3.14 * 12 * g
 Clearing g we have:
 120 / (3.14 * 12) = g
 g = 3.18 cm
 
 The length of the slant height is:
 g = 3.18 cm
