Answer:

The Curved Surface Area of the cone is 427.04cm².

Step-by-step explanation:

Given the height of the cone = 15cm

and the diameter = 16 cm  

We know that d = 2r where r is the radius of the cone.  

Therefore, r = d/2

                    = 16/2

                    = 8 cm  

We know that the Curved Surface Area of the cone =  πrl

and l = √h² + r²

=> l = √(15)² + (8)²

=> l = 17  

Substituting the values in the formula of Curved Surface Area, we get  

CSA = π*8*17

CSA = 427.04cm²  

Therefore, the Curved Surface Area of the cone is 427.04cm².
