Question

Q2 IF A SPHERE IS JUST ENCLOSED BY A CYLINDER OF RADIUS FAND HEIGHT FIND
THE RATIO OF SURFACE AREA OF SPHERE AND CURVED SURFACE AREA OF CYLINDER​

Answer 1

Answer:

1 : 1

Step-by-step explanation:

Surface area of the sphere = 4*π*Rsquare

CSA of cylinder= 2πRh

=4*π*Rsquare. ( h= 2R because the sphere is touching both the up and down side of the cylinder)

therefore the ratio is

1:1
