Geometry Flashcards
The space occupied by a flat shape or the surface of an object.
Area
continuous line forming the boundary of a closed geometric figure
Perimeter
sum of all area of a 3-dimensional shape
surface area
the amount which can be held, as measured in cubic units.
Volume
the distance measured around a circle
circumference
area of square
A=s^2
perimeter of a square
P=4s
Area of rectangle
A=lw
perimeter of rectangle
P= (2l)+(2w)
where l=length and w=width
Area of a trapezoid
A= 1/2 [(a+b) x h]
Perimeter of a trapezoid
P= a + b + c + d
Area of triangle
A= bh/2
where b= base, h= height
Perimeter of triangle
P= a + b + c
Area of parallelogram
A=bh
perimeter of a parallelogram
P= 2a + 2b
Volume of a cube
V=s^3
Surface area of a cube
SA= 6s^2
volume of an irregular prism
V=bh
Volume of a right circular cone
V=1/3 (pi)(r^2)(h)
