A captain looks out of his ship's round porthole. Curious, he measures it and calculates that it has a circumference of 56.52 inches. What is the porthole's diameter? Use 3.14 for π. If necessary

Respuesta :

Answer:

diameter ≈ 18 inches

Step-by-step explanation:

The circumference (C) of a circle is calculated as

• C = πd ( d is the diameter )

given C = 56.52 and using π ≈ 3.14 , then

3.14d = 56.52 ( divide both sides by 3.14 )

d ≈ [tex]\frac{56.52}{3.14}[/tex] ≈ 18 inches
