 Shape Formulas for Area (A) and Circumference (C) Triangle A = bh = x base x height Rectangle A = lw = length x width Trapezoid A = (b1 + b2)h = x sum of bases x height Parallelogram A = bh = base x height Circle

 Figure Formulas for Volume (V) and Surface Area (SA) Rectangular Prism V = lwh = length x width x height SA = 2lw + 2hw + 2lh       = 2(length x width) + 2(height x width) + 2(length x height) General Prisms V = Bh = area of base x height SA = sum of the areas of the faces Right Circular Cylinder V = Bh = area of base x height SA = 2B + Ch = (2 x area of base) + (circumference x height) Square Pyramid Right Circular Cone Sphere

 Equations of a Line Standard Form:Ax + By = Cwhere A and B are not both zero Slope-Intercept Form:    y = mx + b or y = b + mxwhere m = slope and b = y-intercept Point-Slope Formula:
