A. The ratio of the circumference of a circle to its diameter

B. Approximated to be 3.14

C. Approximated to be 22/7

D. The ratio of the radius of a circle to its circumference

Answer 1

Option D.The ratio of the radius of a circle to its circumference

Explanation:

Verify each statement

A) The ratio of the circumference of a circle to its diameter

The statement is True

Because

`C=\pi D`

so

`\pi=C/D`

B) Approximated to be 3.14

The statement is True

Because
`\pi=3.14159265...`

C) Approximated to be 22/7

The statement is True

Because

`(22)/(7)=3.1423`

D) The ratio of the radius of a circle to its circumference

The statement is not True

Because

`(r)/(2\pi r)=(1)/(2\pi)`
