## Convex

Hull

A convex hull is the shape that is formed by the points in a set that are all located within a certain distance of the median point of the set. The distance between each point and the median point is called the radius of the set.

## Projections

Projections are estimates of future events or trends. They are often created by economists, analysts, and other professionals who use data and analysis to make informed guesses about the future. Projections can be used to inform decisions about everything from business planning to public policy.

There are a variety of different types of projections, but most can be classified as either trend or scenario projections. Trend projections assume that past trends will continue into the future, while scenario projections involve making a number of different guesses about what could happen.

Many projections are probabilistic, meaning that they involve estimating the likelihood of different outcomes. This can be done using a variety of methods, such as probability theory or decision analysis.

Projections are often used in conjunction with forecasting, which is the process of using past data and trends to make predictions about the future. Forecasting is a key part of making projections, and the two terms are often used interchangeably.

Projections are also used in financial planning, where they can be used to estimate future income and expenses. This can help individuals and businesses make informed decisions about things like budgeting and investing.

Projections are also used by governments to help inform policymaking. For example, economists might use projections to estimate the impact of a new policy on the economy. This information can help policymakers make informed decisions about whether a policy is likely to be successful.

Projections are also used by businesses to help with strategic planning. By

## Geometrical Properties

A square has four equal sides and four right angles.

## What is a Pentagonal Prism?

A Pentagonal Prism is a prism with 5 faces, each of which is a pentagon.

## What is a Prism?

A prism is a transparent body with flat surfaces that refract light.

## Properties of a Pentagonal Prism

A pentagonal prism is a five-sided prism with two congruent pentagonal bases. The pentagonal prism has 10 faces (5 triangular and 5 square), 20 edges, and 10 vertices.

## Types of Pentagonal Prisms

There are four types of pentagonal prism: right, oblique, acute, and obtuse.

Right Pentagonal Prism

The right pentagonal prism is a five-sided prism in which all the sides are right angles. The base is a pentagon, and the height is the length of the slant height. This is the most common type of pentagonal prism.

Oblique Pentagonal Prism

The oblique pentagonal prism is a five-sided prism in which not all the sides are right angles. The base is a pentagon, and the height is the length of the slant height. This type of prism is not as common as the right pentagonal prism.

Acute Pentagonal Prism

The acute pentagonal prism is a five-sided prism in which the angles at the base are all less than 90 degrees. The base is a pentagon, and the height is the length of the slant height.

Obtuse Pentagonal Prism

The obtuse pentagonal prism is a five-sided prism in which the angles at the base are all greater than 90 degrees. The base is a pentagon, and the height is the length of the slant height.

## What is a Regular Pentagonal Prism?

A regular pentagonal prism is a five-sided prism with pentagonal bases. The length of each side of the base is the same, and the height of the prism is the length of the side of the base multiplied by the slant height.

## What is a Rectangular Pentagonal Prism?

A rectangular pentagonal prism is a five-sided prism with a rectangular base and pentagonal sides. The length of the sides are twice the length of the base.

## Surface Area of a Pentagonal Prism

A pentagonal prism is a prism with five faces, each a pentagon. The surface area of a pentagonal prism is:

A = 5 (b + h)

where a is the surface area, b is the base length, and h is the height.

## Volume of a Pentagonal Prism

The volume of a pentagonal prism is equal to the product of the base area and the height.

Volume = (base area) x (height)
