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.

Orlov [11]

Answer:

<em> 4/12 and 6/18</em>

Step-by-step explanation:

Given the fraction 2/6

We are to write  2 different equivalent fractions that are the same as 2/6

To do this, we will multiply the numerator and denominator of the fraction by same constant. Multiply the numerator and denominator by 2 will give;

2/6 * 2/2

= (2*2)/(6*2)

= 4/12

Also multiplying by a value of 3

= 2/6 * 3/3

= (2*3)/(6*3)

= 6/18

<em>Hence the 2 different equivalent fractions are 4/12 and 6/18</em>
