Answer 1

The answer should be C

Answer 2

D

Explanation:

By definition, π is defined to be the ratio of a circle's circumference to its diameter. In other words:

`\displaystyle \pi=(C)/(d)`

In fact, if you multiply both sides by the diameter d, you can see that:

`C=\pi d`

Which is the formula for circumference you've been commonly taught.
