This is because when we do verification of an
identity, we must work separately on both sides, and to see in the end
if we can get an equality. Because if we square both sides, that already means
that we assume that the equality exist in the beginning, so no need to
verify the identity. 
        
                    
             
        
        
        
Answer:
The volume of the cone is;
100 π inches^3
Step-by-step explanation:
To calculate the volume, we need the height 
We can get the height from the slant height and the radius 
Mathematically, we use Pythagoras’ theorem for this as the slant height, the radius and the height forms a right-angled triangle 
The right-angled triangle has the slant height as its hypotenuse 
By the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides 
Let the height be h
Thus;
12^2 = 5^2 + h^2
169= 25 + h^2
h^2 = 169-25
h^2 = 144
h = √1144 inches = 12 inches 
The volume of the cone is;
1/3 * π * r^2 * h
= 1/3 * π * 5^2 * 12 
= 100 π inches^3
