Multiple choice The area of a circle is 2464 square metres. What will be its circumference? 132m 176m 231m 272m Reveal answer Fill a bubble to check yourself B Correct answer Explanation Area = πr² = 2464. Using π ≈ 22/7: r² = 2464 × 7/22 = 784, so r = 28m. Circumference = 2πr = 2 × (22/7) × 28 = 176m. Option A incorrectly uses only πr, C seems to use wrong π value, and D is miscalculated.
