The answer is Dilation of a scale factor of 4 followed by a reflection of the y axis.
Step-by-step explanation:
On the smaller triangle, the line EF has a length of 1 unit.
On the larger triangle, the line EF has a length of 4 units.
Therefore, the smaller triangle was dilated by 4, since 4x1 is 4.
The triangles was flipped over the y axis.
This means that it was reflected over the y axis.

Answer:
Step-by-step explanation:
The area of a circle varies directly as the square of its radius.
If r₁ = 2in, A₁ = 12.568 in₂, r₂ = 6.4 in, A₂ = ?
ATQ,
So, the new area of the circle is 
.
