Question

1. the circumference of a circle is c centimeters. the diameter of the circle is 13 centimeters. which expression best represents the value of π? a. \\(\frac{c}{6.5}\\) b. \\(\frac{6.5}{c}\\) c. \\(\frac{c}{13}\\) d. \\(\frac{13}{c}\\)

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter.

Step2: Substitute given diameter

Given \( d = 13 \) cm, so \( C = \pi \times 13 \).

Step3: Solve for \( \pi \)

Rearrange the formula: \( \pi = \frac{C}{13} \).

Answer:

C. \(\frac{C}{13}\)
