Question

PLEASE HELP!! If the dimensions of a circle are increased by a factor of 3 (tripled), how will the area of the circle be affected?

Answer 1

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

Answer 2

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.
