1. Geometry Unit Formula Sheet
Area of Circle
Area of Parallelograms
A = π r 2 d 2 d 2
A = bh
A = π x x
Area of Rectangle & Square
Area of Trapezoid
A = (b + b )h
A = lw 1 2
(b & b are the
parallel lines) 2 1 2
Area of Triangle
Circumference of Circle
A = bh
C = πd
C = 2 π r 2
Pythagorean Theorem
Perimeter C
a + b = c 2 2 2 A
Add all Sides
(a x a) + (b x b) = (c x c) B
Surface Area of Cylinder
Surface Area of Cube
SA = 6s 2
SA = 2(π r ) + (2 π r)h 2
=2(π x r x r) + (2π r)h
6(s x s)

Volume of Cylinder
V = π r h 2
SA= 2((lw)+(lh)+(hw))
= (π x r x r)x h
Volume of Rectangular
Prism
Volume of Cube 3
V = S
V = l w h
V = S x S x S
