Question

π is the ratio of the circumference to the diameter of a circle. which expression is equivalent to π? complete the equation. π = ? (with options c/d, d/c, c·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 definition into an equation

By the definition, the ratio of circumference to diameter is \( \frac{C}{d} \), so \( \pi=\frac{C}{d} \).

Answer:

\( \frac{C}{d} \) (corresponding to the option with \( \frac{C}{d} \))
