Worked Solution
Step 1: Find the full circumference of the circle.
C = 2 × π × r = 2 × 22/7 × 14
Step 2: Simplify. 14 ÷ 7 = 2, so C = 2 × 22 × 2 = 88 cm.
Step 3: A quarter circle has an arc that is ¼ of the full circumference.
Arc length = 88 ÷ 4 = 22 cm.
Final answer: 22 cm.
Answer: 22 cm
Correct answer: 22 cm
