Question

Show if the total surface area of a sphere is same that of the total lateral surface of a right circular cylinder and if that is enclosed.

Answer 1

hey mate here is ur answe answeranswer____ Let the radius of the sphere be r cm. Then,Surface area of the sphere = 4πr² cm²　　　　　 　　　　　　 ...(i) The radius and height of a right circular cylinder that just encloses the sphere of radius r and 2r respectively.Surface area of the cylinder = 2πr x 2r= 4πr² cm²　　　　　　　　...(ii) From (i) and (ii), we haveSurface area of the sphere is equal to the surface area of the cylinder that just encloses the sphere.

Answer 2

Answer:

Explanation:

hey mate!!!

i think you have started the basics of area and volume

yes this can also be a higher standard question if asked

and i am glad you asked this question

so here is your answer

___________________________________________

Let the radius of the sphere be r cm.

Then,

Surface area of the sphere = 4πr² cm²             ...(i)

The radius and height of a right circular cylinder that just encloses the sphere of radius r and 2r respectively.

Surface area of the cylinder = 2πr x 2r

= 4πr² cm²        ...(ii)

From (i) and (ii), we have

Surface area of the sphere is equal to the surface area of the cylinder that just encloses the sphere.
