Question

The circle of area 5 cm² is scaled uniformly by factor 2, then what is the area of transformed figure?

Answer 1

Answer:

I not know answer of this question

Answer 2

Answer:

Step-by-step explanation:

Here , Area of circle is 5cm²= Area.

If a transformation matrix is scaled by factor 2,

it will become

D = $\left[\begin{array}{ccc}2&0\\0&2\end{array}\right]$

Determinant of A is 4.

$A_{t}$ = Area * determinant D

= 20 cm²
