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

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
