A traditional unit of length in Japan is the ken (1 ken = 1.97 m). What is the volume of a cylindrical water tank of height 5.67 kens and radius 5.59 kens in (a) cubic kens and (b) cubic meters?

The volume of a cylinder is calculated by the product of pi, radius to the power of two and the height of the object. It is expressed as:

V = pi (r^2) h

We calculate as follows:

V = pi (5.59^2) (5.67) = 556.62 kens^3

V = 556.62 kens^3 (1.97 m / 1 ken) = 1096.54 m^3
