  2. $154$ m
  3. $176$ m

  4. None of the above

A Correct answer
Explanation

Area = pi * r^2 = 2464. r^2 = 2464 * 7 / 22 = 112 * 7 = 784. r = sqrt(784) = 28. Diameter = 2 * r = 56 m.

AI explanation

The area of a circle is found using the formula Area = pi * r^2. Setting this equal to the given area results in (22/7) * r^2 = 2464. Multiplying both sides by 7/22 gives r^2 = 784, so the radius is the square root of 784, which is 28 m. The diameter is twice the radius, giving 56 m.
