Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
वर्तुळाची त्रिज्या = 5 सेमी
केंद्रावर वर्तुळपाकळी द्वारे आंतरित कोन = 60°
वापरलेले सूत्र:
वर्तुळपाकळीचे क्षेत्रफळ = (π × R2 × θ)/360°
गणना:
वर्तुळपाकळीचे क्षेत्रफळ = (π × R2 × θ)/360°
⇒ (22/7) × (5)2 × 60°/360°
⇒ (22 × 25)/(7 × 6)
⇒ (11 × 25)/21 = 13.09 ≈ 13.1 सेमी2
∴ योग्य उत्तर 13.1 सेमी2 आहे.
