(i) Surface area of sphere = 4πr², where r is the radius of sphere
(ii) As Height of cylinder, h = r+r =2r
And Radius of cylinder = r
CSA of cylinder formula = 2πrh = 2πr(2r) (using value of h)
(iii) Ratio between areas = (Surface area of sphere)/CSA of Cylinder)
= 4r2/4r2 = 1/1
Therefore, Ratio of the areas obtained in (i) and (ii) is 1:1.
