Radius is half of the circle diameter is the whole thing inside the circle since it is a radius, and it is a half of the full circle, we need to double out that number, and multiply by 2. so here, you said it is 28 take 28, and multiply by 2, if you do every thing correctly, you should get: 56 so then answer would be 56 centimeters. Hope that this helps you! =)
First of all, it is a ratio. I know that for a fact, but not very sure about the candy part. What I think it means is that they are comparing two types of candy.
