Difficulty: Easy
Correct Answer: 17.60 m
Explanation:
Introduction / Context:
Converting between a circle’s area and circumference requires finding the radius from area and then applying the circumference formula.
Given Data / Assumptions:
Concept / Approach:
Area A = πr^2 ⇒ r = sqrt(A/π). Circumference C = 2πr.
Step-by-Step Solution:
Verification / Alternative check:
Using π = 22/7 gives a close value; rounding will still land near 17.6 m, consistent with the option set.
Why Other Options Are Wrong:
14.64 m, 16.36 m, and 18.40 m do not match the computed circumference from the given area.
Common Pitfalls:
Skipping the square root stage or mixing up the formulas for area and circumference can cause major errors.
Final Answer:
17.60 m
