# 11.3 Volume of a Prism / Cylinder

# 11. 3

• (1-19) all
• Volume of a Prism or Cylinder = BH
• B = area of the base which means that B will be substituted with one of the following formulas depending on what shape(s) your base(s) is/are:
• A of a triangle = 1/2 bh
• A of a parallelogram = bh
• A of a trapezoid = 1/2 (b1 + b2) h
• A of a regular polygon = 1/2 asn
• A or a kite = 1/2 d1 * d2
• A of a circle= pi r ^2
• A of a sector = a/360 * pi r^2
• A of a segment = a/360 - 1/2 bh
• A of an annulus = pi (R^2 - r^2)
