Question

On my paper, there's a circle drawn inside of a square, whose side length is 12. I have to find diameter, radius, area, area in terms of pi, ...
For the diameter first of all, would it be 12? Or do I have to subtract?
Thanks.

Answer 1

Yes. The diameter is 12.

Answer 2

So then, :
Would the radius be 6?
Would the area be 354.9456? or 113.04?

Answer 3

You're right about the radius = 6. And your second answer is correct for the area.

The area is PI * r^2.

3.14 * 36 = 113.04.

Answer 4

Thanks.
