2/4 can be simplified to 1/2 just divide with the common factors of both N and D :)
You basically dilate the slope of y to the slope of x by the same scale factor at which all the sides of the triangles are dilated or increased/decreased by.
If 2 parallel lines are cut by a transversal, then alternate interior angles are congruent.

Sorry but where is the table my screen does not show it
Answer:
8
Step-by-step explanation:
Recall these two equations for circumference and diameter.
Circumference = 2*pi*radius
Diameter = radius*2
25.12 = 2*pi*radius
Radius = 4
Diameter = 4*2 => 8
Thus the diameter is 8
