The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
What is a cloesed plane figure having all points an equal distance from the center?
It is a circle or a sphere
Is it true that all points of a sphere are equal distances to its center.?
Yes, it is true. In a perfect geometric sphere, all points on its surface are equidistant from its center. This property is one of the defining characteristics of a sphere.
What is the largest circle that can be drawn around a sphere such as a globe?
That's called a "great circle" of the sphere. -- It's any circle whose center is at the center of the sphere. -- Its diameter is equal to the diameter of the sphere. -- Its area is equal to 1/4 the surface area of the sphere. -- The shortest distance between any two points on the sphere is along the piece of the great circle on which they lie. (There's only one, unless the two points are the opposite ends of a diameter.)
Is All points of a sphere are equal distances to its center?
yes it is! Good Job!
