I don't know the exact question but heres the best i got 
the surface area would be 294 inches
one face would be 49 inches 
and the volume would be 343
        
             
        
        
        
The sector of the circle formed by its two radius of length 12 inches has an area of 24 pi. This is obtained using the formula, Area is equal to the product of pi, radius squared and central angle all over 360.
        
             
        
        
        
Answer:
4;64
5;125
Step-by-step explanation:
Find the cube of the number
E.g. (5x5)x5
 =25x5
 =125
 
        
                    
             
        
        
        
You add the 4 to both sides of the equation.
        
             
        
        
        
Answer:
x = 16
Step-by-step explanation:
  SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.
The angles opposite to equal sides are equal. 
   ⇒  ∠STR  = ∠R
        ∠STR = 4x - 28
Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair
∠STR + ∠STU = 180°    {linear pair}
 4x - 28 + 9x = 180
4x + 9x - 28  = 180      {Combine like terms}
        13x- 28 = 180 
Add 28 to both the sides
           13x    = 180 + 28
            13x  = 208
Divide both sides by 13
               x = 208/13
