    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

    r = radius

    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)
