D=5.4 ft circumference

5.4 feet ≈ 16.96 feet

Step-by-step explanation:

We see that the diameter is 5.4 feet. The circumference of a circle is given by the formula: , where d is the diameter. Here, d = 5.4, so:

C = * 5.4

Thus, the answer is 5.4 feet or 16.96 feet.

Hope this helps!

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
