The distance around a circular dance hall room is 135 feet. Which of the following is closest to the longest distance across the dance hall?

Respuesta :

Answer:

CD = [tex]\frac{135}{\pi }[/tex]

Step-by-step explanation:

distance around a circular = CIRCUMFERENCE LENGTH = [tex]2 * \pi * r[/tex]

CL = [tex]2 * \pi * r[/tex]

135 = [tex]2 * \pi * r[/tex]

longest distance = circumference diameter (CD) = [tex]2 * r[/tex]

135 = [tex]2 * \pi * r[/tex]

135 = CD * [tex]\pi[/tex]

CD = [tex]\frac{135}{\pi }[/tex]
