Question

what is the total surface area and the curved surface area of sphere please please please tell it's very urgent

Answer 1

hey mate,
here is your answer....

• TSA of sphere = CSA of shpere....i.e. 4πr^2....

hope it helps...

Answer 2

A sphere has just one surface only, that is curved, not plane.

So, curved surface area & total surface area of a sphere is the same

For sphere surface area is or curved surface area & total surface area = 4*pi*r^2.

Curved surface area of sphere = 2πr × 2r=4πr^2
