The circumference of a circle is 158 km. Find the diameter. Use pi= 3.14 *

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.

x= 149. 24+7=31. 180-31=149
