Answer:
There was 62.23% change in radius as the ion formed.
Step-by-step explanation:
Given
Radius of Aluminium 
atom = 143 pm
Radius of Aluminium 
atom = 54 pm
Change is the radius = Radius of Aluminium atom - Radius of Aluminium atom = 143 -54 = 89
Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium atom and multiply by 100 we get
% Change is the radius = 
Hence there was 62.23% change in radius as the ion formed.
The answer is 16

Drop comments if any doubt arises.
Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in
Circumference of circle= 2πr so, 2×5×π= 31.4 in
A rotation transformation is where you turn a figure about a given point. The point about which the object is rotated can be inside the figure or anywhere outside it. There must be no change in shape or size of the object.
A reflection of an object is the 'flip' of that object over a line, called the line of reflection.
A translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.
All these three transformations are rigid - preserve the figure sizes.
A dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.
Answer: dilation maps the large triangle onto the small triangle
