Question

What will this problem look like? The radius, r, of a circle is one-half of the length of its diameter, d.

1. 1/2r= d

2. 2r=d

3. 1/2 + r = d

4. r= 1/2d

5. r= d/2

There is more than one answer

Answer 1

2. 2r=d
4. r= 1/2d
5. r= d/2

Answer 2

r = 1/2d

r = d/2.......d/2 is the same as 1/2d

2r = d
