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

Step-by-step Solution: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

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

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

The formula for circumference of a circle using radius

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

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

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