Hi CG and Manunkind,

Just a minor point, (though my English teacher certainly wouldn't say so.) But when tidying up the questions can you add full stops after answers? I'm not saying that you don't, but so many answers don't have them.

As a sometime writer/journalist, these things irritate.

Seeing fewer and fewer mistakes, so great work by you both.

Circles are two dimensional. Surface is a three dimensional concept. Two dimensional objects do not have surfaces. A circle can have an area or a perimeter (circumference). Here's how I would rewrite it:

When you double the diameter of a circle, how does its area change?

Errr ... No.

"Area" and "Surface" are synonyms.

Although you're right otherwise.
The area enclosed in a circle is called a Disk.

The question should be :
When you double the diameter of a disk, how does its area change?

Changes made. Thanks again to all of you.
