C = 2πr

P = a + b + c

l = length

w = width

b = base

h = height

s = slant height

r = radius

d = diameter

P = perimeter

C = circumference

A = area

SA = surface area

Atriangle = bs

Abase = πr2

Abase = b2

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 areasof all the faces

SA = the sum of the areasof all the faces

V = × (area of base) × h 13

V = × (area of base) × h 13

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

orSA = 2(wh + lw + lh)
