When we increase the area of a circle, the increase in the radius is not directly proportional to the percentage increase in the area. The relationship between the area and the radius of a circle is nonlinear. However, we can calculate the approximate increase in the radius in terms of percentage using the following formula:Percentage Increase in Radius ≈ √(Percentage Increase in Area)In this case, the percentage increase in area is 32%. Let's calculate the approximate increase in the radius:Percentage Increase in Radius ≈ √(32%)Percentage Increase in Radius ≈ √(0.32)Percentage Increase in Radius ≈ 0.5657To express this as a percentage, we can multiply by 100:Percentage Increase in Radius ≈ 0.5657 * 100 ≈ 56.57%Rounded to the nearest whole percentage, the approximate increase in the radius is 57%, which is closest to 32% among the provided answer choices.So, the correct answer is approximately 32%, considering rounding.
