Kk

Answer 1

`7` (see assumption below)

Explanation:

Assuming you meant "what is the diameter of a circle with a circumference of 22 using 22/7 as pi

The circumference (`color(blue)C`) of a a circle with diameter `color(red)d` is given by the relation:
`color(white)("XXX")color(blue)C=picolor(red)d`

This can be re-arranged as
`color(white)("XXX")color(red)d=color(blue)C/pi`

Using the supplied values
`color(white)("XXX")color(red)d=22/(22/7)=22xx7/22=7`
