Answer:
Approximately 50.318 km.
Step-by-step explanation:
To find the diameter of a circle, you use the equation C = pi x d, where the d stands for diameter.
First, you'd plug in the 158 for C, so you have 158 = pi x d.
Since we are using 3.14, it would be 158 = 3.14 x d, and so then we'd divide both sides by 3.14 to isolate the variable d.
158/3.14 gives you approximately 50.3184713376, though rounded to the nearest thousandths, 50.318.
