Answer :
(i) SA of sphere =4πr2
(i) SA of sphere =4πr2(ii) Height =r+r=2r
(i) SA of sphere =4πr2(ii) Height =r+r=2rradius =r
(i) SA of sphere =4πr2(ii) Height =r+r=2rradius =r⇒Curved Surface Area=2πrh=2πr(2r)=4πr2
(i) SA of sphere =4πr2(ii) Height =r+r=2rradius =r⇒Curved Surface Area=2πrh=2πr(2r)=4πr2(iii) Ratio =4πr24πr2=11 or 1:1
