Question

The circumference of a circular rug is about 18.84 feet, and the diameter ofthe rug is 6 feet.Which expression best represents the value of ne?A.B.O c.OD.

Answer 1

Remember that

The circumference of a circle is equal to

`C=\pi\cdot D`

where

D is the diameter

Solve for pi

`\begin{gathered} C=\pi\cdot D \\ \pi=(C)/(D) \end{gathered}`

substitute given values

`\pi=(18.84)/(6)`

The answer is option C
