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
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
= 9π
= 9A1
So we can conclude that the area of the circle be increase by 9 times.
Hope it will find you well.
