Answer options

  1. 5:4
  2. 25:16
  3. 6:7
  4. 9:13

Correct answer and explanation

Correct answer: 25:16

Explanation: āœ… Correct Answer: B. 25:16 šŸ“š Explanation: The area of a circle is calculated using the formula pi multiplied by the square of the radius. Therefore, the ratio of the areas is equal to the square of the ratio of the radii. For a radius ratio of 5:4, the area ratio is (5 multiplied by 5) to (4 multiplied by 4), which is 25:16. This is a basic geometric property involving squares of proportions.
