The answer would be 48.
All you would have to do is multiply the height (the straight line) and the length which is the 6.
        
                    
             
        
        
        
Answer:
The surface area of the cone is 126π cm².
Step-by-step explanation:
The surface area of a cone can be found using this formula:
 
- where r = radius and l = slant height 
In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.
Substitute these values into the formula for the surface area of a cone.
The surface area of the right cone is 126 π cm².
 
        
             
        
        
        
Answer:
Step-by-step explanation:
In Δ AFB,
∠AFB + ∠ABF + ∠A = 180   {Angle sum property of triangle}
 90 + 48 + ∠1 = 180
        138 + ∠1 = 180
                  ∠1 = 180 - 138
∠1 = 42°
FC // ED and FD is transversal
So, ∠CFD ≅∠EDF   {Alternate interior angles are congruent}
      ∠2 = 39°
In ΔFCD,
∠2 + ∠3 + ∠FCD = 180
39 + ∠3 + 90 = 180
          129 +∠3 = 180
                    ∠3 = 180- 129
∠3 = 51°     
 
        
             
        
        
        
6,782 is the nearest root.
The nearest integer would be 7.
