Area Formulas
-
Parallelogram Area Formula:
- Calculated using ( A = bh )
- ( b ) represents the base, and ( h ) the height.
-
Triangle Area Formula:
- Given by ( A = \frac{1}{2}bh )
- The base ( b ) is multiplied by the height ( h ), then halved.
-
Trapezoid Area Formula:
- Expressed as ( A = \frac{1}{2}(h)(b1 + b2) )
- ( h ) is the height, while ( b1 ) and ( b2 ) are the lengths of the two bases.
-
Circle Area Formula:
- Defined by ( A = \pi(r^2) )
- ( r ) indicates the radius of the circle.
Circumference Formula
-
Circle Circumference Formula:
- Represented by ( C = d(\pi) )
- ( d ) denotes the diameter of the circle, which is multiplied by ( \pi ).
