h = Altitude in linear units
Example:
Find the volume of a rectangular pyramid whose base is 3" x 4" and whose altitude
is 6".
Area of the base = 3 x 4 = 12 square inches
Volume of a Cylinder
where
V = Volume in cubic units
A = Area of the base in square units
h = Altitude in linear units
r = Radius of the base
d = Diameter of the base
Example:
Find the volume of a cylindrical tank whose diameter is 9'6" and whose height
is 11'6".
