Calculate the curved surface area of the cone .
[tex]\bf \underline{ \underline{Formula \: applied : }}[/tex]
Curved surface area of cone = πrl
[tex]\bf \underline{ \underline{Solution : }}[/tex]
First of all,
Radius = Diameter/2
=> Radius,r = 14/2
=> Radius,r = 7 cm
Now,
[tex] \sf{Curved \: surface \: area \: of \: cone =\pi rl}[/tex]
[tex] \sf \: \implies \: \dfrac{22}{ \cancel7} \times \cancel7 \times 8.45[/tex]
[tex] \sf\implies22 \times 8.45[/tex]
[tex] \sf \implies 185.9 \: {cm}^{2} [/tex]
Hence,the Curved surface area of cone is 185.9 cm².
