P = 2l + 2w

or

P = 2(l + w)

C = πd

or

C = 2πr

P = a + b + c

l = length

w = width

b = base

h = height

s = slant height

d = diameter

P = perimeter

C = circumference

A = area

SA = surface area

V = volume

A = πr2

A = lw

A = bh 2

Atop = πr 2

1 2

Atriangle = bs

Abase = πr 2

Abase = b 2

SA = 2bs + b2

Aside = 2πrh

SA = 2πr2 + 2πrh

V = (area of base) × h

V = (area of base) × h

V = (area of base) × h SA = the sum of the areas of all the faces

SA = the sum of the areas of all the faces

V = × (area of base) × h 1 3

V = × (area of base) × h 1 3

SA = wh + wh + lw + lw + lh + lh

or SA = 2(wh + lw + lh)

Pythagorean Theorem

c2 = a2 + b2

Equation of a line:

y = mx + b

Ax + By + C = 0

y – y1 = m(x – x1)
