कागदाच्या चौरस शीटचे क्षेत्रफळ = 784 सेमी 2
वर्तुळाची संख्या = १६
संकल्पना:
मासिकपाळी
सूत्र वापरले:
स्क्वेअर पेपरची बाजू = √पेपरच्या स्क्वेअर शीटचे क्षेत्रफळ
एकूण वर्तुळांची संख्या = (बाजू × बाजू)/ (व्यास × व्यास)
गणना:
चौरस कागदाची बाजू = \(√ {784} = \;\) 28 सेमी
प्रत्येक वर्तुळाचा व्यास = d
एकूण वर्तुळांची संख्या = \(\frac{{28 × 28}}{{d × d}}\) ⇒ d = 7 सेमी
\( \Rightarrow 16 = \frac{{784}}{{{d^2}}}\)
तर,
प्रत्येक वर्तुळाची त्रिज्या = 7/2 = 3.5 सेमी
प्रत्येक वर्तुळाची परिमिती = 2 × 22/7 × 3.5 = 22 सेमीLast updated on Jul 8, 2025
