→ POINTS TO BE NOTED
- SURFACE AREA OF THE CYLINDER IS ALSO KNOWN AS TOTAL SURFACE AREA
- A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder.
nd, to find Surface area of cylinder there is one formula
[tex] \pink{ \boxed{ \sf2 \pi \: r(h + r)}}[/tex]
[tex]\purple{\rule{15mm}{2.9pt}} \red{\rule18mm{2.5pt}} \orange{ \rule18mm{2.5pt}}[/tex]
★Here
- r( RADIUS) = 3cm
- h(HEIGHT)= 5cm
★ Let's solve:-
[tex] \sf \: ↦2 \pi \times 3(5 + 3) \\ \sf \:↦ 2\pi \times 15 + 9 \\ \sf \:↦ 2\pi \times 24 \\ \sf \: ↦48\pi\:cm²[/tex]
[tex]\purple{\rule{15mm}{2.9pt}} \red{\rule18mm{2.5pt}}\orange{ \rule18mm{2.5pt}}[/tex]
Hence;
- The surface area of the cylinder=48πcm²
