The diameter of a sphere (1 point)

is the distance from the center of O the sphere to any point on the surface of the sphere.
does not pass through the center of the sphere.
is the longest
• distance on a sphere.
O is half the length of the radius.

The diameter of a sphere is the distance that passes through the center of the sphere and touches two points on the surface of the sphere. It is equal to twice the length of the radius. Hence, the statement that "O is half the length of the radius" is incorrect.
