Detailed Solution
Download Solution PDFदिलेले आहे:
त्रिज्या = 10 मीटर
कोन= 90°
वापरलेली संकल्पना:
त्रिज्याखंडाचे क्षेत्रफळ = \(\rm \frac{πr^2}{360^o} \timesθ\)
येथे,
r = त्रिज्या
θ = त्रिज्याखंडाचा कोन
गणना:
त्रिज्याखंडाचे क्षेत्रफळ = \(\rm π\frac{10^2}{360^o} \times90^o\)
⇒ \(\rm \frac{22}{7} \times\frac{100}{4}\)
⇒ 78.57 ≈ 78.5 मी2
∴ त्रिज्याखंडाचे क्षेत्रफळ 78.5 मी2 आहे.
