Answer:

4.3π or 13.51 = r

Step-by-step explanation:

C=2πr To find the circumference of a circle, you must have the formula

8.6π = 2πr      Substitute the C for 8.6π

4.3π = r           Divide both sides by 2π

13.51 = r         Simplify 4.3π if needed

Given that the reason for the missing statement, it means that the similarlity statement is equal to it self.

Having proved in statement 3 that <span>∠AEC ≅ ∠BDC both being right angles, it can be seen that the angle both have in common is angle C.

Thus, to statement 4 shows that angle C is congrent to itself.

Therefore, the missing statement in step 4 is </span><span>∠ACE ≅ ∠ACE</span>
