Is circumference larger than radius

Answer 1

Yes it is. Circumference is the whole area of the circle. Radius is from the middle to the side of the circle.

Yes it is. The radius it half way across the circle from the center, while the circumference is all the way around the circle. The diameter is all the way across the circle, while being twice the radius. The circumference is about 3.14 times the diameter (or Pi if you prefer).
