Formulas and Mathematical Situations
Here you will find information on specific formulas needed in order to understand relations between numbers you see in a textbook, and real life aplications
Distance Formula
Base Area
Surface Area
Volume
Surface area is the total space of the exterior of a three-dimensional shape.
It would also be the area of the 2 dimensional shapes the 3D figure would become if it had been flattened out into a net.
It is better to understand than to memorize, however here are some examples of formulas for surface area:
Cube: 6s2
Sphere: 4Ï€r2
The volume of a solid refers to its capacity, as in how much fits inside, or how much space it takes up in general.
Some examples of formulas include:
Cube: s3
Sphere: 4/3Ï€r3
The distance formula is used to calculate the distance between one point (coordinate) from another.
It is derived from the Pythagorean theory since as it is based on the same basic priciapls.
A (squared) + B(squared) = C (squared) turns into AC (squared) = AB (squared) + BC (squared)
Which derivates into the following equation:
Various times seen as B (an uppercase b), base area is self exaplanatory
It is the area of the face of a solid figure called the base and found by the equation of length x height.
