त्रिज्यखंड की त्रिज्या (r) = 7 cm
केन्द्रीय कोण (θ) = 60°
प्रयुक्त सूत्र:
त्रिज्यखंड का क्षेत्रफल = πr2 × \(\dfrac{60}{360}\)
गणना:
त्रिज्यखंड का क्षेत्रफल = \(\dfrac{22}{7}\)× 7 × 7 × \(\dfrac{60}{360}\)
⇒ त्रिज्यखंड का क्षेत्रफल = \(\dfrac{77}{3}\) cm2
∴ त्रिज्यखंड का अभीष्ट क्षेत्रफल \(\dfrac{77}{3}\) cm2 है।
