Answer:
Step-by-step explanation:
<h2>Cone:</h2>
     diameter = 12 cm
                   r =  12 ÷ 2 = 6 cm
                  h = 6 cm
       
                                     
To find the surface area, we need to find the slant 'l'
        
        
                                                          = 3.14 * 6 * (6 + 8.49)
                                                         = 3.14 * 6 * 14.49
                                                         = 273 cm²
