</li><li><p>7.56 cm</p>
</li></ol> <h2 id="content-id-1526037489-5"><b> Mensuration 3D Questions Solution</b></h2><p>The correct answer is <strong>option 1</strong> i.e. <strong>4.16 cm.</strong></p>

<p>Volume of 1 cone = (1/3)πr<sup>2</sup>h = (1/3)π × 3<sup>2</sup> × 4 = 12π cm<sup>3</sup></p>

<p>8 cones volume = 8 × 12π = 96π cm<sup>3</sup> </p>

<p>Volume of sphere = 96π cm<sup>3</sup></p>

<p>Let the radius of the sphere = R cm</p>

<p>(4/3)πR<sup>3</sup> = 96π</p>

<p>⇒ (4/3)R<sup>3</sup> = 96</p>

<p>⇒ R<sup>3</sup> = 96 × 3/4 = 72</p>

<p>⇒ R = â&#136;&#155;72 ≈ 4.16 cm</p>
