Find the curved surface area of a conical tent whose radius is 8 m and height is 6 m.

Concept Used: Curved Surface Area of Cone = πrl


Slant Height of the cone =


Where r = radius of the cone, h = height of the cone, and l = slant height of the cone.


Given: Radius = 8 m


Height = 6 m


Explanation:


Applying the formula for Slant height, we get,


l =


Putting the value of “r” and “h,” we get,


l =


l = √100


l = 10 m


Now putting the value of “l” in the formula of Curved Surface Area we get,


C.S.A = πrl


C.S.A = 3.14 × 6 × 10


C.S.A = 188.4 m2


Hence, The curved surface area of a cone is 188.4 m2.
