The value of x in the congruent triangles abc and dec is 1
<h3>How to determine the value x?</h3>
The question implies that the triangles  abc and dec are congruent triangles.
The congruent sides are:
ab = de
bc = ce = 4
ac = cd = 5
The congruent side ab = de implies that:
4x - 1 = x + 2
Collect like terms
4x - x = 2 + 1
Evaluate the like terms
3x = 3
Divide through by 3
x = 1
Hence, the value of x is 1

The Volume formula of a Cylinder is 
V = 

r²h 
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V = 

(8)²(4)
   = 

256

   ≈ 
804.2 units³ (approximately)
Units
³ because it is a volume (3D shape)
