A sphere has just the one entire surface area.
One if it is solid, two if it is hollow
A sphere has a single curved surface. It is said to have one surface. Further, the sphere has no "flat spots" or "angles" or "discontinuities" of any kind. It is a planar figure that is the set of all points equidistant from a single point, which is its center.A sphere has only one surface.
o no flat surface.
A spree has I lat surface
A sphere has a single face, one surface. A sphere has no corners. Or if you want to think about it from another perspective - a sphere has an infinity number of sides allowing for the curved surface.
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.
Surface Area of a Sphere = 4 pi r2
The surface of a sphere. It cannot be a sphere since points which are not on its surface will be nearer to the centre.
Take the surface area of the sphere as of it was whole, and divide by the amount of the sphere that is missing.
A sphere has less surface with the same diameter.
The formula for the surface area of a sphere is 4*pi*r2
Surface area of sphere is : A= 4*pie*r^2
