Well first of all you spelt pie wrong the mathmetical term of pi is spelt pi. It is also what you use to measure the radius of a circle.

No. Radius is half of the diameter.

(radius+radius) times pi

The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius

It means to multiply the radius by itself: radius x radius

1. It has a radius. 2. It has a diameter. 3. It has a circumference. 4. It has an area. 5. It is two dimensional. 6. It lies in a plane. 7. It has no vertices. 8. It is a closed figure. 9. It has no volume. 10. It is delineated by a curved line. 11. The ratio of circumference to radius is pi.

No. Radius is half of the diameter.

(radius+radius) times pi

When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
