Question

π is the ratio of the circumference to the diameter of a circle. which expression is equivalent to π? complete the equation. π = ? the options are \\(\frac{c}{d}\\), \\(\frac{d}{c}\\), \\(c \cdot d\\)

Explanation:

Step1: Recall the definition of π

The problem states that \( \pi \) is the ratio of the circumference (\( C \)) to the diameter (\( d \)) of a circle.

Step2: Translate the ratio into an expression

A ratio of \( C \) to \( d \) is written as \( \frac{C}{d} \). So from the definition, \( \pi=\frac{C}{d} \).

Answer:

\(\boldsymbol{\frac{C}{d}}\) (corresponding to the first option in the dropdown: \(\frac{C}{d}\))
