1.	If theradius of a cylinder is 4cm.and height is 10cm then total surface area of cylinder is
Answer» GIVEN:- $\rm{Radius\:of\:the\:Cylinder=4cm}$ $\rm{Height\:Of\:the\:Cylinder=10cm}$ TO FIND:- TOTAL Surface area of Cylinder FORMULAE USED:- ${\huge{\boxed{\rm{2\pi r{(r+h)}}}}}$ Where, r = Radius h= Cylinder. Now, $\implies\rm{2\pi r{(r+h)}}$ $\implies\rm{2\times{\dfrac{22}{7}}\times{4}\times{(4+10)}}$ $\implies\rm{2\times{\dfrac{22}{7}}\times{4}\times{14}}$ $\implies\rm{2\times{\dfrac{22}{\cancel{7}}}\times{4}\times{\cancel{14}}}$ $\implies\rm{2\times{22}\times{4}\times{2}}$ $\implies\rm{352sqm^2}$ . Hence, The Total Surface area of Cylinder is 352sqcm² EXTRA INFORMATION. $\rm{Lateral\: Surface\:area\:of\:Cylinder=2\pi rh}$ $\rm{Volume\:of\:Cylinder=\pi r^2h}$ $\rm{Volume\:of\:Cone=\pi r^2\dfrac{h}{3}}$ .
