Question

the circumference of a circle is $c = pi d$. what is the approximate circumference of the circle? (use 3.14 for $pi$.) a. 18.1 ft b. 23.6 ft c. 47.1 ft d. 94.2 ft

Explanation:

Step1: Identificar el diámetro

El diámetro $d = 15$ ft.

Step2: Aplicar la fórmula de la circunferencia

Usamos $C=\pi d$, con $\pi = 3.14$ y $d = 15$. Entonces $C=3.14\times15$.
$C = 47.1$ ft

Answer:

C. 47.1 ft
