Correct answer: B

Step 1: The area of the circle is given as 36π. Using the formula A = πr², we can solve for the radius: πr² = 36π ⇒ r² = 36 ⇒ r = 6.

Step 2: The circumference of the circle is 2πr = 2π × 6 = 12π.

Step 3: The circle is divided into six equal parts, so each arc length is 12π ÷ 6 = 2π.

Thus, the length of the arc of each part is 2π.

हिन्दी उत्तर:

चरण 1: वृत्त का क्षेत्रफल 36π दिया गया है। सूत्र A = πr² का उपयोग करके, हम त्रिज्या ज्ञात कर सकते हैं: πr² = 36π ⇒ r² = 36 ⇒ r = 6।

चरण 2: वृत्त की परिधि 2πr = 2π × 6 = 12π है।

चरण 3: वृत्त को छह समान भागों में विभाजित किया जाता है, इसलिए प्रत्येक चाप की लंबाई 12π ÷ 6 = 2π है।

इस प्रकार, प्रत्येक भाग की चाप की लंबाई 2π है।
