Volume of the cylinder =  
 
Step-by-step explanation:
Radius(r) of the cylinder= 
Height(h) of the cylinder= 
Volume of a cylinder is :
                    
As, 
           
Volume is:  
             
The volume of the cylinder is:

Answer:
x = ± 2
Step-by-step explanation:
Given
f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5
Equating the two gives
x² + 1 = 5 ( subtract 1 from both sides )
x² = 4 ( take the square root of both sides )
x = ±  = ± 2
 = ± 2
Thus (- 2, 5) and (2, 5) are solutions
