Question

he radius and slant height of Cone is 2 cm and 6cm respectively its curved surface

area is ……….........cm².​

Answer 1

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

Answer 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)
