Question

What is the ratio of the radius to the circumference of any circle using 3.14

Answer 1

Hello. I hope you find this helpful. ↓

What do we have to find? : the ratio of the radius to the circumference of any circled using 3.14, or π

— as, the circumference of circle is 2 · π · r ( 2 muplity by
`\pi` multiply br R ) and, the radius of a circle is r, so, the ratio is radius to by circumferen-ce of a circle OR ' r : 2πr '

which is 1 : 2
`\pi` aka 1 : 2 × pi

Answer 2

1/(2 pi) = r/C

Explanation:

The formula for circumference using radius is

C = 2 * pi *r

We want r/C

Divide each side by C

C/C = 2 * pi *r/C

1 = 2 * pi *r/C

Divide by 2 pi

1/(2 pi) = 2/2 * pi/pi *r/C

1/(2 pi) = r/C
