वृत्त की त्रिज्या = 6 सेमी
एक त्रिज्यखंड का केंद्रीय कोण = 40°
प्रयुक्त सूत्र:
त्रिज्यखंड का क्षेत्रफल = \(\theta \over 360°\) × πr2
गणना:
दिए गए त्रिज्यखंड का क्षेत्रफल = \(40° \over 360°\) × π × (6 सेमी)2
⇒ (\(1 \over 9\)× π × 36) सेमी2
⇒ (π × 4) सेमी2
⇒ 4π सेमी2
∴ त्रिज्यखंड का क्षेत्रफल 4π सेमी2 है।
