Question

(HELP PLS??)Arrange the reasons for the proof in the correct order.
Prove: If the diameter of a circle is 6 meters and the formula for diameter is d = 2r, then the radius of the circle is 3 meters.

A. If r ≠ 3 m, then d ≠ 6 m. Since the contrapositive is true, the original statement must also be true. Therefore, if the diameter of a circle is 6 meters, then the radius is 3 meters.
B. Multiplication of real numbers shows that d = 2(2 m) = 4 m.
C. Substitute r = 2 m into d = 2r.
D. Assume that r ≠ 3 m. For example, the radius equals another length, such as r = 2 m.

Answer 1

B.)B, A, C, D
C.)D, A, B, C
D.)D, C, B, A
these are my answer choices.

Answer 2

First we get D.) as we must first assume something at first as our contrapositive.
Then we use this assumed statement to be true and substitute r = 2. So C.) comes next.
Evaluating d = 2(2m) = 4m after the substitution means that B.) comes next.
And lastly, we conclude the proof with contraposition and so A.) comes in last.

So the right choice must be D.)

Answer 3

That makes sense now.Thanks!(:
