Suppose the diameter of a circle is \color{green}{6}6start color green, 6, end color green units. What is its circumference?

C = 6pi or approximately 18.84

Step-by-step explanation:

If the diameter is 6 units, we can find the circumference is found by

C = pi * d

C = 6 pi

If we use the approximation for pi of 3.14

C = 6*3.14

C =18.84

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
