The circumference (C) of a circle is 16 cm. Which formula can you use to find the
diameter (d) if you know that C = 3.14d?​

Respuesta :

The formula is used to find the diameter of circle is: [tex]d = \frac{C}{3.14}[/tex]

The diameter of circle is 5.1 cm

Solution:

Given that,

Circumference (C) of a circle is 16 cm

The formula for circumference of circle when diameter is given is:

[tex]C = \pi d\\\\\pi \text{ is a constant equal to 3.14}\\\\C = 3.14d[/tex]

Rearrange the formula to get "d"

Divide both sides by 3.14

[tex]d = \frac{C}{3.14}[/tex]

The above formula is used to find the diameter of circle

Given that, circumeference = C = 16 cm

Substituting we get,

[tex]d = \frac{16}{3.14}\\\\d = 5.095 \approx 5.1[/tex]

Thus diameter of circle is 5.1 cm
