Step-by-step Solution:

  • Circumference of a circle can be computed using the formula [tex]C\:=\:\pi d[/tex] , where [tex]C[/tex] represents the circumference, [tex]d[/tex] represents the diameter, and [tex]\pi =3.14[/tex].
  • In case, we have the radius to deal with instead of the diameter, just multiply it by [tex]2[/tex] to determine the diameter.

We can also use the formula for circumference of a circle using radius, which will be [tex]C = 2\pi r[/tex]

So,

The formula for circumference of a circle using diameter

  • [tex]C\:=\:\pi d[/tex]

From above formula,  [tex]\pi[/tex] can be computed as

  • [tex]\pi = \frac{C}{d}[/tex]

From above formula, diameter [tex]d[/tex] can be computed as

  • [tex]d = \frac{C}{\pi}[/tex]

The formula for circumference of a circle using radius

  • [tex]C = 2\pi r[/tex]

From here, [tex]\pi[/tex] can be computed as

  • [tex]\pi = \frac{C}{2r}[/tex]

So, [tex]r[/tex] can be computed as

  • [tex]r = \frac{C}{2 \pi}[/tex]

Therefore, the options B, C, D and E are correct.

Answer:

B, C, D, and E

Step-by-step explanation:

The formula for the circumference of a circle is

[tex]C = \pi \: d[/tex]

Or

[tex]C = 2 \pi \: r[/tex]

When we solve for r in the latter, we obtain:

[tex]r = \frac{C}{2 \pi} [/tex]

When we solve for π in the former, we get:

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

If we solve for π in the latter, we get;

[tex]\pi = \frac{C}{2r} [/tex]

If we solve for d, in the former, we get

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

Therefore the correct options are:

B, C, D , and E
