37.714 cm^2
radius=2 cm
slant height=6 cm
curved surface area = πrl.
= 22/7 × 2×6
= 44/7×6
=264/7
=37.714 cm^2

Solution :
For the given cone ;
• Radii of the cone is 2 cm .
• Slant height of the cone is 6 cm .
The curved surface area of a cone is π r l
=> π × 2 × 6
=> 12 π cm²
=> 36.8 cm²
Answer : The curved surface area of the cone is 36.8 cm²
__________________________________
Additional Information :
Volume of a cone - ⅓ π r² h
Total surface area of a cone : π r l + π r²
Volume of a cylinder : π r²h
Lateral surface area of a cylinder - π r²h
Total surface area of a cylinder : 2 π r( h + r)
