ఇచ్చింది:

శంఖువు యొక్క వక్ర ఉపరితల వైశాల్యం = 2 × శంఖువు యొక్క భూమి వైశాల్యం

ఉపయోగించబడిన భావన:

ఉపయోగించబడిన సూత్రం

శంఖువు యొక్క వాలు ఎత్తు (l). = √r2 + h2

శంఖువు యొక్క CSA = πrl

గణన:

శంఖువు యొక్క వ్యాసార్థం r యూనిట్లుగా అనుకుందాం.

πrl = 2πr2

⇒ l = 2r

⇒ r = 6√3/2

⇒ r = 3√3

శంఖువు యొక్క వాలు ఎత్తు (l) = √r2 + h2

⇒ 6√32 = 3√3+ h2

⇒ h2 = 108 - 27 = 81

⇒ h = 9 సెం.మీ

∴ సమాధానం 9 సెం.మీ.
