Question

what is total surface area of sphere and curved surface area of sphere​

Answer 1

For a sphere Total Surface Area ( TSA ) = Curved Surface Area (CSA)

Formula => 4πr²

hope it helps !!

Answer 2

AnswEr:

• A sphere doesn't have flat surface, edges and vertices. It has only curved surface.

So,

• Surface area of sphere is 4πr².

• The surface area of a sphere is that the total area covered by the surface of a sphere in a three dimensional space.

Some Additional Information:

• Sphere: A sphere is defined as the set of points that is at equal distances from a common point in three dimensional space.

• Examples of sphere in real life is ball, moon and planet etc.

• A sphere doesn't have any sides or flat surfaces.

• A sphere is a symmetrical object.

Formulas related to it :

• Volume of sphere = 4/3 πr³
• Curved surface area of hemisphere = 2πr²
• Total surface area of sphere = 3πr²
• Volume of hemisphere = 2/3 πr³
