Measurements

Geometric measurements and properties are essential in understanding various shapes and their characteristics. The perimeter of a circle, known as its circumference, is calculated using the formula 2πR.

Measurements

Volume

Pyramids and Cones
V= 1/3Bh
General Prism or Cylinders
Formula: V=Bh
Formula: V=Bh
Measures the amount of space enclosed within the boundry

Surface Area

Sphere
Formula: S=4piR2
Right Circular Cone
Formula: SA=piR2+piRs
Right Regular Pyramid
Formula: SA=B+1/2ps
Right Prisms and Cylinders
Formula: SA=2B+ph
The extent of a 2-dimensional surface enclosed within a boundary

Circumfrence

Formula: 2piR
The perimeter of a circle is called the circles circumfrence

Square Units

We use square units becuase it is uniform or the same when compared. It is also easier to use than it would be for example a circle.
