Download Solution PDFఇచ్చినది:
వ్యాసార్థం = 10 మీ
కోణం = 90°
ఉపయోగించిన భావన:
చాపం యొక్క వైశాల్యం = \(\rm \frac{πr^2}{360^o} \timesθ\)
ఇక్కడ,
r = వ్యాసార్థం
θ = చాపం కోణం
గణన:
చాపం యొక్క వైశాల్యం = \(\rm π\frac{10^2}{360^o} \times90^o\)
⇒ \(\rm \frac{22}{7} \times\frac{100}{4}\)
⇒ 78.57 ≈ 78.5 మీ2
∴ చాపం యొక్క వైశాల్యం 78.5 మీ2.
