Question

Find the surface area of the cylinder. Type an exact answer in terms of pi.

Answer 1

~150.8

Explanation:

surface area of a cylinder=2 pi r h + 2 pi r²

Answer 2

`\large{\boxed{\mathfrak\pink{\fcolorbox{pink}{pink}{Answer:-}}}}`

→ POINTS TO BE NOTED

1. SURFACE AREA OF THE CYLINDER IS ALSO KNOWN AS TOTAL SURFACE AREA
2. 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

`\pink{ \boxed{ \sf2 \pi \: r(h + r)}}`

`\purple{\rule{15mm}{2.9pt}} \red{\rule18mm{2.5pt}} \orange{ \rule18mm{2.5pt}}`

★Here

• r( RADIUS) = 3cm
• h(HEIGHT)= 5cm

★ Let's solve:-

`\sf \: ↦2 \pi * 3(5 + 3) \\ \sf \:↦ 2\pi * 15 + 9 \\ \sf \:↦ 2\pi * 24 \\ \sf \: ↦48\pi\:cm²`

`\purple{\rule{15mm}{2.9pt}} \red{\rule18mm{2.5pt}}\orange{ \rule18mm{2.5pt}}`

Hence;

• The surface area of the cylinder=48πcm²
