Question

A traditional unit of length in Japan is the ken (1 ken 1.97 m). What are the ratios of (a) square kens to square meters and (b) cubic kens to cubic meters? What is the volume of a cylindrical water tank of height 5.50 ken

Answer 1

If 1 ken is 1.97 meter, then 1 square ken is 3.8809 square meters, and one cubic ken is 7.645373. As for the cylindrical tank, the volume of it would be 10.835 times the radius of the cylinder time 1.97^2 times pi. As you didn't specify the radius, I can't give the exact answer but that would be how to get it.

Answer 2

Part a)

`A = 3.88 m^2`

Part b)

`V = 7.64 m^3`

Step-by-step explanation:

1 ken = 1.97 m

Part a)

square ken = ______square m

now we can say

`A = 1 ken^2`

`A = 1 (1.97 m)^2`

`A = 3.88 m^2`

Part b)

cubic Ken = _____cubic meter

now we can say

`V = 1 ken^3`

`V = 1 (1.97 m)^3`

`V = 7.64 m^3`
