The formula for the surface area of a pentagonal pyramid is given by A = (1/2)Pl + B, where A is the surface area, P is the perimeter of the base, l is the slant height, and B is the area of the base. The formula for the volume of a pentagonal pyramid is given by V = (1/3)Bh, where V is the volume, B is the area of the base, and h is the height of the pyramid. **

To draw an oblique view of a pentagonal pyramid, start by drawing a horizontal line for the base of the pyramid. Then, draw the five sides of the pyramid extending upward from the base, making sure to keep the lines slanting at an angle to show the oblique view. Next, connect the top of the sides to form the apex of the pyramid. Finally, add any additional details or shading to give the drawing depth and dimension. **

The formula for the volume of a regular pentagonal pyramid is V = (1/3) * B * h, where V represents the volume, B is the area of the base, and h is the height of the pyramid. The area of the base (B) can be calculated using the formula B = (1/4) * s * √(5(5+2√5)) * s^2, where s is the length of one side of the base. The height (h) is the perpendicular distance from the base to the apex of the pyramid. **

In Islam, the concept of wasting money or being frivolous with wealth is discouraged. While physical coins have a tangible value and can be used for charitable purposes, virtual currency does not have the same physical presence. However, the principle of not being wasteful with wealth still applies. Therefore, throwing virtual currency, especially in a manner that is disrespectful or wasteful, would likely be considered haram. It is important to be mindful of how we use and treat our wealth, whether it is physical or virtual. **

In most countries, it is not forbidden to hoard currency in the form of coins. However, hoarding large amounts of coins may raise suspicion and could potentially be seen as an attempt to avoid taxes or engage in illegal activities. Additionally, some countries have laws that limit the amount of coins that can be used in a single transaction, so hoarding large amounts of coins may not be practical for everyday use. It's always best to check the specific laws and regulations in your country regarding currency hoarding. **

In numismatics, the inscription on a coin refers to the text or words that are typically found on the coin. These inscriptions can include the name of the ruler or issuing authority, the date of minting, and sometimes religious or symbolic phrases. Inscriptions on coins are important for identifying the coin's origin, historical context, and sometimes even its value. Studying these inscriptions is a key aspect of numismatics as it helps researchers and collectors understand the significance and history of the coin. **
