LSA(CSA) TSA & VOLUME of solid Figures

Name of the Solid	LSA(CSA)in sq.units	TSA in sq.units	VOLUME in cubic units
CYLINDER	$2{\pi }rh$ Where r is the radius of circular base	$2{\pi }r(r+h)$ where "h" is the height of cylinder	${\pi }r^{2}h$
CONE	${\pi }rl$ Where l is the slant height	${\pi }r(l+r)$ Where r is the radius of circular base	${\frac {1}{3}}{\pi }r^{2}h$ Where h is the height or depth of the cone
