A right circular cylinder of radius r cm and height h cm (h>2r) just encloses a sphere of diameter
R cm
2r cm
H cm
2h cm
A solid cylinder of radius r and height h is placed over other cylinder of same height and radius. The total surface area of the shape so formed is
4πrh + 4πr2
4πrh − 4πr2
4πrh + 2πr2
4πrh − 2πr2
