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	$2{\pi }rh$	$2{\pi }r(r+h)$ where "h" is the height of cylinder	${\pi }r^{2}h$
CONE	${\pi }rl$ Where l is the slant height	${\pi }r(l+r)$	${\frac {1}{3}}{\pi }r^{2}h$
FRUSTUM OF CONE	${\pi }(r_{1}+r_{2})l$ Where l=${\sqrt {h^{2}+(r_{1}-r_{2})^{2}}}$	Failed to parse (syntax error): {\displaystyle π{{(r_{1}+r_{2})l+r_{1}^2+r_{2}^2}}} Where l=${\sqrt {h^{2}+(r_{1}-r_{2})^{2}}}$	${\frac {1}{3}}{\pi }h(r_{1}^{2}+r_{2}^{2}+r_{1}r_{2})|-|SPHERE|<math>4{\pi }r^{2}$	$4{\pi }r^{2}$	${\frac {4}{3}}{\pi }r^{3}$
