Answer:
V = L^3      where v is volume and L the length of one side
A = 6 * L^2    total area of cube with side L
A = 6 * V^2/3      area of cube expressed in V
A2 / A1 = (V2 / V1)^2/3       6 cancels
A2 / A1 = 8^2/3 = 4      ratio of areas
 
        
             
        
        
        
Answer:
b=5

Answer:
8pi
Step-by-step explanation:
circumference of the circle=2 pi r(radius)
 =2pi×d(diameter)/2
 =2 × pi × 8/2
 =8 pi cm
 
        
             
        
        
        
The 3 inside angles need to equal 180 degrees.
Angle K is given as 48 degrees.
Angle M would be 90 degrees.
Angle J = 180 - 90 - 48 = 42
Angle J = 42 degrees
