Formulas for Area A, Perimeter P, Circumference C, and Volume V Square A = s2 P=4s s = length of side Rectangle A=lw P = 2l + 2w l = length w = width Circle A = p r2 C=2pr r = radius Sector of a Circle Triangle h = height b = base Trapezoid h = height b1 and b2 are called bases Parallelogram A=bh P = 2a + 2b b = base; h = height a = side Pythagorean Theorem a2 + b2 = c2 c = hypotenuse a and b are called sides or legs Cube A = 6 s2 V = s3 s = side or edge Rectangular Solid V=lwh A=2lw+2lh+2wh l = length; w = width;
