Percent Proportions
IS = PERCENT
OF = 100
Area of parallelograms (rectangles, rhombuses, and squares)
A = BH
Area of a trapezoid
A=(base 1+base 2)/2 *H
Area of a triangle
A = 1/2 BH
Pythagorean Theorem
a2+b2 =c2
Circumference of a circle
C=π2r
Area of a circle
A = πr^2
Volume of a rectangular prism
V = BH
Volume of a Triangular Prism
V = 1/2BH of the triangle* height of the prism
Volume of a cylinder
V = πr^2h
Volume of a cone
V = 1/3 πr^2h
Volume of a pyramid
V = 1/3 Bh
Volume of a sphere
4/3 πr^3
Surface Area of a cube
A=6a^2
Surface Area of a rectangular prism
A = 2(wl+hl+hw)
Surface Area of a Triangular Prism
Triangular sides: 1/2Bh
Rectangular sides: lw
Add the area of all sides to get the surface area
Surface Area of a cylinder
A = 2πr(r + h)
Surface Area of a Sphere
A = A=4πr^2
