Question

Is the Curved surface area and Total surface area of a sphere the same?​

Answer 1

Answer:

no C.S.A and T.S.A are differnet and have different formulas according to geometric figures

Step-by-step explanation:

Answer 2

Sphere have No curved surface area , it has only Total surface area , since it is a closed figure ...

TSA of sphere = 4πr²

Volume of sphere = 4/3(πr³)

But , Hemisphere have both CSA & TSA.

CSA of Hemisphere = 2πr²

TSA of Hemisphere = 3πr²

Volume of Hemisphere = 2/3(πr³)
