History of Area
The area now known as the Bronx was originally inhabited by the Siwanoy band of the Lenape Native Americans. The area was called Rananchqua by the Siwanoy, meaning “the place where we hunt deer”. The Dutch called the area Bronck’s Landt, after Jonas Bronck, who settled there in 1639. The first English settlers arrived in 1643.
The Bronx was part of Westchester County until 1874, when it was annexed to New York City. The Bronx was an independent borough of New York City from 1898 to 1974, when it was merged with Manhattan and Brooklyn to form the current City of New York.
Definition of Area
An area is a measure of how much space is inside a defined boundary. It is usually measured in square units, such as square meters or square feet. The area of a shape is the number of square units it takes up.
Area Formulas
The area of a rectangle is the product of its length and width.
The area of a square is the product of its length and width.
The area of a triangle is one-half the product of its base and height.
What are 3D Shapes?
3D shapes are shapes that have three dimensions. They are able to be seen from different angles and can be touched.
Area of 3D Shapes Formula
The area of a 3D shape can be found by using the following equation:
A = l × w × h
Where:
A = Area
l = Length
w = Width
h = Height
Area Formula for Different Shapes
There is no one-size-fits-all answer to this question, as the area formulas for different shapes can vary significantly. However, some general formulas that can be used to calculate the area of different shapes include:
For a rectangle: Area = length x width
For a square: Area = length x length
For a triangle: Area = base x height / 2
For a circle: Area = π x radius2
Formulas for 3D Shapes
There are many formulas that can be used to calculate the dimensions of 3D shapes. Some of the most common formulas are listed below.
Sphere:
Radius: R
Volume: V = 4/3 π R3
Cylinder:
Radius: r
Height: h
Volume: V = π r2 h
Pyramid:
Base Length: b
Height: h
Volume: V = 1/3 bh
