I can't tell if this is what you were asking for, but I included some explanations.

Answer:

the area of the circle be increase by 9 times.

Explanation:

As we know that the area to find the Are of a circle is:

  • A1= π
    r^(2) where r is the radius of the circle.

From the above formula, only the radius (r) is the dimension.

So if the dimensions of a circle are increased by a factor of 3, it means the new radius is: 3r

Hence, we have a new area:

  • A2 = π
    (3r)^(2) = 9π
    r^(2) = 9A1

So we can conclude that the area of the circle be increase by 9 times.

Hope it will find you well.
