Download Solution PDFअवधारणा:
आकार की लंबाई = AB + BC + चाप CD
गणना:
दिया गया है:
∵ Cos 60° =\(\frac{20}{BC}\)
⇒\(\frac{1}{2}\) =\(\frac{20}{BC}\)
⇒ BC = 40 mm
अर्धवृत्त का परिमाप = π × त्रिज्या
⇒ चाप BC की लंबाई = π × त्रिज्या
⇒ चाप BC की लंबाई = π × 14 = 44 mm
∴ आकार की लंबाई = AB + BC + चाप CD = 50 + 40 + 44 = 134 mm
