Answer:
The area of the new circle is
Step-by-step explanation:
Given:
radius of the circle = 3 in.
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared.
Let
z-----> the scale factor
x-----> the area of the enlarged circle
y-----> the area of the original circle
So;
In this problem we have
----> the scale factor
The area of the original circle is equal to
Now substituting value of y and solve for x we get;
Hence Area of the new Circle is
Also The area of the enlarged circle is 16 times the area of the original circle.
